Storage boxes promise order and deliver it only when they fit: the wrong box wastes bed space, rattles, or blocks the tonneau cover you already own. Periea boxes are well known in home storage, but truck buyers need to know where they fit and where a truck-specific box does the job better. This guide reviews Periea honestly, then compares four verified truck bed boxes that actually fit. See the full Storage Boxes archive for the category. More in this family: our subcategory archive and the parent category archive.
The 30-second answer
Start with the Periea verdict below for home and cab storage, then buy the UnderCover SwingCase SC104D for Silverado and Sierra beds, the SwingCase SC404P for Tundra passenger-side storage, the SwingCase SC205P for Super Duty trucks, and the SwingCase SC300P for Ram beds without RamBox.
How we researched this guide
We compared 5 storage box options, then checked maker and listing documentation for each finalist: UnderCover SwingCase listings (ABS plastic construction, 75 lb capacity, key-lockable lid, 3-inch tonneau clearance, 1-year promise; fitments for Silverado and Sierra, Tundra, Super Duty and Ram) and Periea brand research (collapsible home and boot storage boxes, fabric construction, no stable US Amazon truck-bed listing found). Only truck boxes with a verifiable listing and published fitments carry buttons below.
We also reviewed owner reports on the SwingCase listings and storage discussions, paraphrased and linked in each product block. Periea coverage comes from home-storage reviews rather than truck-bed testing, and we say so plainly. No box was fitted for this guide and no capacity numbers were invented; every figure below comes from a maker or listing specification.

Storage box finder: match a box to your truck
Weight bands: at or below 75 lb (34 kg) go to the SwingCase for your truck; over 75 lb go to that same truck's SwingCase with an over-capacity warning, because no SwingCase in this guide is rated above 75 lb. Periea boxes carry no truck-box weight rating in this guide and are for home and car-boot loads only. Every result recommends a pick from this guide, with its button.

How to choose a truck storage box
Vehicle fitment first
Storage boxes are vehicle-specific: part numbers encode make, model, year range and side. Ordering by looks instead of part number wastes the purchase, and side matters as much as model since driver and passenger boxes differ. Confirm truck, year and bed side before ordering, because every SwingCase here fits one side of specific trucks only.
Swing-out versus fixed
Swinging boxes bring gear to you over the tailgate, which matters on tall beds and saves climbing. Fixed boxes maximise volume but demand reaching in. Choose by how often you retrieve gear, not by volume alone. A swing-out box wins when you reach tools daily, while a fixed box suits loads you rarely move between jobs.
Security
A key-lockable lid turns a box from a container into storage. Open beds invite opportunistic theft, and a lock that actually latches matters more than a lid that merely closes. A lock deters casual theft but does not make a box a safe, so keep valuables out of any bed box overnight.
Tonneau compatibility
If you run a tonneau cover, clearance decides the purchase. SwingCase boxes keep 3 inches of clearance for virtually all tonneau types, but confirm your specific cover and box combination before ordering. Check tonneau clearance with the lid closed, because a box that fouls the cover helps nobody however well it fits.
Capacity and volume
A 75 lb capacity with about 2 cubic feet suits towing supplies, rescue kits and tools. Heavier gear belongs lower in the box and, beyond the rating, in the bed itself rather than forcing the box. Weigh a typical load before buying, since the 75 lb SwingCase limit covers tools and recovery gear only up to that weight.
Fabric versus hard boxes
Fabric boxes suit indoor and cab organisation; hard ABS boxes suit open beds, weather and security. Matching material to exposure is the single most common storage mistake, and the Periea verdict above shows why. Fabric boxes fold away when empty, while hard boxes protect better but occupy the bed even when they hold nothing.

Reviewed Honestly: Periea Collapsible Storage Boxes
Reviewed Honestly
Why the Periea Collapsible Storage Boxes is our pick
Periea makes collapsible fabric storage boxes that work well for home organisation and car boots: fold-flat when empty, carry handles, and compartments for everyday items. What Periea does not offer, on the evidence we found, is a truck-bed-specific box with a vehicle fitment list, a lockable lid, or a tonneau clearance specification. That matters, because a fabric boot box in an open truck bed soaks, blows and offers no security. We review Periea honestly rather than forcing a truck verdict it cannot support.
Periea Collapsible Storage Boxes key specs
- Brand: Periea
- Type: collapsible fabric storage boxes
- Use: home and car boot organisation
- Design: fold-flat when empty
- Handles: carry handles per brand pattern
- Compartments: divided per model
- Truck-bed fitment: none published
- Lockable lid: not a Periea truck feature
- Tonneau clearance: not specified
- US Amazon truck listing: none stable found
- Best for: home and cab storage
- Warranty: brand standard
Periea Collapsible Storage Boxes: fits and best for
Periea boxes fit home storage, closets and car boots where a collapsible fabric box is exactly right. They fit truck cabs as organisers for small items, kept out of weather. They do not fit open truck beds as primary storage, where weather, security and tonneau clearance demand a hard, lockable, vehicle-specific box like the SwingCases below.
Periea Collapsible Storage Boxes pros and watch-outs
- Fold-flat when empty
- Good for home and boot use
- Light and easy to carry
- Compartment organisation
- Honest value for indoor use
- No truck-bed fitment list
- Fabric will not survive open-bed weather
- No lockable truck security
Periea Collapsible Storage Boxes: what owners report
Owner coverage for Periea comes from home-storage reviews, where buyers praise the fold-flat design and everyday organisation, not from truck-bed use. That absence is itself the finding: no credible truck-bed owner record exists for Periea boxes. See the verified alternative linked in this block, which carries the truck-bed owner record. Further owner discussion: Garage Journal tool forums; the listing carries the owner reports paraphrased above.
Periea Collapsible Storage Boxes: who should not buy
Skip Periea for open truck-bed storage entirely. Buy a vehicle-specific hard box below, and keep Periea for the house or the cab.
Periea Collapsible Storage Boxes: pair it with
Pair a Periea cab organiser with a SwingCase bed box so small items stay in the cab and tools stay locked in the bed.
Exact-fit note: this item is sold mainly through pro-supply and dealer channels with no stable US Amazon listing, so we do not link a guess. Verified alternative with the same job in mind: UnderCover SwingCase SC104D Truck Bed Storage Box.

Best for Silverado and Sierra: UnderCover SwingCase SC104D, Silverado and Sierra 1500 Driver Side
Best for Silverado and Sierra
Why the UnderCover SwingCase SC104D, Silverado and Sierra 1500 Driver Side is our pick
UnderCover’s SwingCase is the truck-bed answer to the Periea question: a hard ABS plastic box that swings out over the tailgate for access, lifts out without tools, and stands upright on its own. The SC104D fits 2019 to 2023 Chevrolet Silverado and GMC Sierra 1500 driver-side beds, holds up to 75 lb, locks with a key, and keeps 3 inches of clearance for virtually all tonneau covers. It is storage that works with the truck rather than against it.
UnderCover SwingCase SC104D, Silverado and Sierra 1500 Driver Side key specs
- Part number SC104D
- Fit: 2019 to 2023 Silverado and Sierra 1500
- Side: driver

UnderCover SwingCase SC104D, Silverado and Sierra 1500 Driver Side: fits and best for
This box fits 2019 to 2023 Silverado and Sierra 1500 driver-side beds, and suits owners who want tools, towing supplies and tie-downs locked and organised without losing bed use. The swing-out design means gear comes to you instead of demanding a climb into the bed. Check your bed and tonneau combination before ordering, since fitment is vehicle-specific.
UnderCover SwingCase SC104D, Silverado and Sierra 1500 Driver Side pros and watch-outs
- Swings out for easy access
- Removable without tools
- Key-lockable lid
- 75 lb capacity

UnderCover SwingCase SC104D, Silverado and Sierra 1500 Driver Side: what owners report
Owners on the listing praise the swing-out access most, describing gear retrieval without climbing into the bed, and note the tonneau clearance works with their existing covers. The recurring watch-out is fitment discipline: ordering the wrong side or year range wastes the purchase. Reports are paraphrased from the listing linked in this block. Further owner discussion: Garage Journal tool forums; the listing carries the owner reports paraphrased above.
UnderCover SwingCase SC104D, Silverado and Sierra 1500 Driver Side: who should not buy
Skip this part number if your truck is not a listed Silverado or Sierra 1500, or if you need the passenger side; order the matching part for your truck.

Best for Tundra: UnderCover SwingCase SC404P, Tundra Passenger Side
Best for Tundra
Why the UnderCover SwingCase SC404P, Tundra Passenger Side is our pick
The SC404P brings the SwingCase pattern to the 2023 to 2025 Toyota Tundra passenger side, excluding trucks with Trail Edition boxes. The same high-impact ABS construction, 75 lb capacity, key-lockable lid and swing-out access apply, with a shape sized to the Tundra bed. For Tundra owners tired of gear sliding around an open bed, this is the fitted answer.
UnderCover SwingCase SC404P, Tundra Passenger Side key specs
- Part number SC404P
- Fit: 2023 to 2025 Toyota Tundra
- Side: passenger
- Excludes: Trail Edition boxes
- Material: high-impact ABS plastic
- Capacity: 75 lb
- Lid: key-lockable
- Tonneau clearance: 3 inches per line pattern

- Promise: 1 year per maker
- Maker: UnderCover
UnderCover SwingCase SC404P, Tundra Passenger Side: fits and best for
This box fits 2023 to 2025 Tundra passenger-side beds without Trail Edition boxes, and suits owners who carry towing supplies, rescue kits and tools. The swing-out design keeps the bed free for larger loads while small gear stays organised and locked. Confirm the Trail Edition exclusion before ordering.
UnderCover SwingCase SC404P, Tundra Passenger Side pros and watch-outs
- Tundra-specific fit
- Swing-out access
- Key-lockable lid
- 75 lb capacity
- Removable and portable
- Excludes Trail Edition boxes
- Passenger side only for this part
- Vehicle-specific fit only
UnderCover SwingCase SC404P, Tundra Passenger Side: what owners report
Owner coverage for the Tundra SwingCase follows the line pattern: praise for swing-out access and tonneau compatibility, with fitment discipline as the watch-out. Coverage specific to the SC404P is thinner than for the long-running Silverado part, so we lean on the shared SwingCase documentation here. See the listing linked in this block. Further owner discussion: Garage Journal tool forums; the listing carries the owner reports paraphrased above.
UnderCover SwingCase SC404P, Tundra Passenger Side: who should not buy
Skip this part if your Tundra has Trail Edition boxes, or if you need the driver side; order the matching part instead.
UnderCover SwingCase SC404P, Tundra Passenger Side: pair it with
Pair it with the driver-side Tundra SwingCase for balanced, organised bed storage.

Best for Super Duty: UnderCover SwingCase SC205P, Ford Super Duty Passenger Side
Best for Super Duty
Why the UnderCover SwingCase SC205P, Ford Super Duty Passenger Side is our pick
The SC205P fits 2017 to 2025 Ford F-250 and F-350 Super Duty passenger-side beds, bringing the SwingCase pattern to heavy-duty trucks whose owners carry serious towing and recovery gear. The 75 lb capacity, key-lockable lid and tonneau clearance carry over, and the swing-out design matters more on a tall Super Duty bed, where climbing in for a strap or shackle is a real chore. It is the Super Duty storage answer.
UnderCover SwingCase SC205P, Ford Super Duty Passenger Side key specs
- Part number SC205P
- Fit: 2017 to 2025 Ford F-250 and F-350 Super Duty
- Side: passenger

- Capacity: 75 lb
- Lid: key-lockable
- Tonneau clearance: 3 inches
- Removable: no tools
- Best for: Super Duty beds
- Promise: 1 year per maker
- Maker: UnderCover
- Install: per maker guidance
UnderCover SwingCase SC205P, Ford Super Duty Passenger Side: fits and best for
This box fits Super Duty passenger-side beds across a long model range, and suits owners who tow and recover with heavy gear. The swing-out access is especially valuable on tall beds, and the lockable lid secures towing supplies. Confirm your model year and side before ordering, since Super Duty beds vary across the range.
UnderCover SwingCase SC205P, Ford Super Duty Passenger Side pros and watch-outs
- Super Duty specific fit
- Swing-out access on tall beds
- Key-lockable lid
- 75 lb capacity
- Tonneau-compatible
- Passenger side only for this part
- Long model range needs year checking
- Uses bed wall space
UnderCover SwingCase SC205P, Ford Super Duty Passenger Side: what owners report
Owners of SwingCase boxes on heavy-duty trucks praise the same swing-out access and tonneau compatibility as other fitments, with the tall-bed benefit noted most. Coverage specific to the SC205P is thinner than for the Silverado part, so shared line documentation carries weight here. See the listing linked in this block. Further owner discussion: Garage Journal tool forums; the listing carries the owner reports paraphrased above.
UnderCover SwingCase SC205P, Ford Super Duty Passenger Side: who should not buy
Skip this part if your truck is not a listed Super Duty, or if you need the driver side.
UnderCover SwingCase SC205P, Ford Super Duty Passenger Side: pair it with
Pair it with a driver-side SwingCase for balanced storage on a working Super Duty.
We may earn a commission at no cost to you.
Tip: load heavy towing gear low in the box so the swing action stays smooth. See also our guide to Best Tool Chest Under 300.
Best for Ram: UnderCover SwingCase SC300P, Ram Passenger Side
Best for Ram
Why the UnderCover SwingCase SC300P, Ram Passenger Side is our pick
The SC300P fits 2002 to 2023 Ram 1500 and 2003 to 2020 Ram 2500 and 3500 passenger-side beds without RamBox, with 2 cubic feet of storage inside the familiar SwingCase pattern. The same ABS construction, 75 lb capacity, key-lockable lid and swing-out access apply, and the no-RamBox condition matters: RamBox beds already have their own storage, and this box is for trucks without it. For Ram owners with a plain bed, this is the fitted answer.
UnderCover SwingCase SC300P, Ram Passenger Side key specs
- Part number SC300P
- Fit: Ram 1500 2002 to 2023, Ram 2500 and 3500 2003 to 2020

- Ram-specific fit
- 2 cubic feet of storage
- Swing-out access
- Key-lockable lid

Owner coverage for the Ram SwingCase follows the line pattern, with swing-out access and tonneau compatibility praised and fitment discipline as the watch-out.

Further owner discussion: Garage Journal tool forums; the listing carries the owner reports paraphrased above.
UnderCover SwingCase SC300P, Ram Passenger Side: who should not buy

Fitment and installation basics
Confirm part number, model year, bed configuration and side before ordering, including exclusions like Trail Edition boxes and RamBox beds. Installation for SwingCase boxes uses self-tapping screws into the bed wall per the listing, and the box should swing freely and latch securely before any gear goes in. See our guide to best tool chest under 300 for the larger storage that complements bed boxes.
Load thoughtfully: heavy towing gear low, frequently used items accessible, and total weight within the 75 lb rating. A box loaded beyond its rating strains its mount and swing mechanism, and gear sliding inside damages both box and contents. Our best tow ropes under 50 guide covers the towing kit that belongs in a bed box.
Keep the lid locked when parked, check the mount screws periodically, and keep the box clean and dry inside. A bed box that rattles, sticks or leaks needs attention before it becomes a bed box that fails on the road. See best overlanding tool kits for the kit organisation that pairs with bed storage.

Safety essentials
- Never exceed the box’s rated capacity; overload strains mounts and latches.
- Secure the lid and latch before driving; an open box spills gear onto the road.
- Keep the box clear of the tonneau mechanism so covers open and close freely.
- Do not store fuel, flammables or unsecured heavy objects in a bed box.
- Check mount screws periodically; vibration loosens fixings over time.
- Keep children clear of swinging boxes during fitting and use.
Three picks from this guide support safe storage: a lockable Silverado box, a Tundra box with tonneau clearance, and a Super Duty box that keeps heavy gear low and secure.
Periea Collapsible Storage Boxes: Good home and boot boxes, but not truck-bed boxes; buy the verified alternative for bed use.
UnderCover SwingCase SC104D, Silverado and Sierra 1500 Driver Side: A swinging, removable bed box for 2019 to 2023 Silverado and Sierra 1500, driver side.
UnderCover SwingCase SC404P, Tundra Passenger Side: A swinging bed box for 2023 to 2025 Tundra passenger side, excluding Trail Edition boxes.
Troubleshooting
| Symptom | Likely cause | Fix |
|---|---|---|
| Box will not swing freely | Mount misalignment or overload | Check mounting, reduce load, re-align per the maker guide |
| Lid will not latch | Overfilled box or damaged latch | Reduce contents, inspect and clean the latch |
| Box rattles while driving | Loose mount screws | Tighten screws to the maker specification and recheck |
| Tonneau cover will not close | Clearance conflict with the box | Confirm the 3-inch clearance combination before forcing the cover |
| Gear slides inside the box | No internal organisation | Add dividers or pouches for small items |
| Water inside the box | Lid seal or drainage issue | Inspect the seal, dry contents, check lid alignment |
Who should NOT buy these storage boxes
Open-bed buyers should not buy fabric boxes. Fabric soaks, blows and offers no security in an open bed. Periea boxes belong indoors or in the cab, and the SwingCases below belong in the bed.
RamBox owners should not buy the SC300P. RamBox beds already carry their own storage, and this box is explicitly for trucks without it. Check the bed walls, not the badge, before ordering.
Nobody should order by looks alone. Part number, year range and side decide fitment, and a beautiful box for the wrong truck is a return, not storage.
Overloaders should not buy any bed box as a bulk store. A 75 lb box holds a kit, not a workshop. Heavy gear belongs in the bed itself, secured properly.

FAQ
Are Periea storage boxes good for truck beds?
No, not as primary bed storage. Periea boxes are collapsible fabric organisers that suit home and car-boot use, but they carry no truck-bed fitment list, no lockable lid and no tonneau clearance specification. Truck beds need hard, vehicle-specific boxes like the SwingCases in this guide.
What is a SwingCase truck bed box?
A hard ABS bed box that swings out over the tailgate for access, lifts out without tools, and stands upright on its own. It holds up to 75 lb, locks with a key, and keeps 3 inches of clearance for virtually all tonneau covers.
How do I know which SwingCase fits my truck?
By part number, which encodes make, model, year range and side. Check your truck against the listing’s fitment, including exclusions like Trail Edition boxes and RamBox beds, and confirm driver versus passenger side.
Will a SwingCase work with my tonneau cover?
SwingCase boxes are designed with 3 inches of clearance for virtually all tonneau types: soft, hard, folding and rolling. Confirm your specific cover and box combination before ordering, since unusual covers can still conflict.
Can I install a SwingCase myself?
Yes for most owners: installation uses self-tapping screws into the bed wall per the listing, and the box swings and latches for testing before gear goes in. If you are unsure about drilling your bed, a professional installer can fit it quickly.
Can I remove a SwingCase and carry it?
Yes: the box lifts out without tools and stands upright on its own, so gear travels with you to the job site and the bed stays free for larger loads when needed.
What should I store in a truck bed box?
Towing supplies, rescue kits, tie-downs, tools and small gear within the 75 lb rating. Heavy gear belongs low in the box, and flammables or unsecured heavy objects do not belong in a bed box at all.
Driver side or passenger side: does it matter?
Yes, the boxes differ by side and are not interchangeable. Order the part number for the side you want, and consider a pair for balanced storage if you carry gear on both sides.
Do bed boxes affect bed capacity?
They use a section of bed wall, but swinging boxes preserve most bed use since they sit against the wall and lift out. Fixed crossover boxes consume more bed space, so swinging boxes suit owners who still haul large loads.
