The best camper shell tool box depends on where you can mount it and what you need to store. Among these options, the VEVOR underbody box is best for buyers seeking a flexible rear-of-camper or rack installation, while VEVOR’s steel tongue boxes suit trailer or RV setups. A portable CRAFTSMAN box works for smaller hand tools. The gas struts are not a toolbox, but may be relevant when replacing compatible lift supports on a camper-shell hatch.
| Product | Best For | Key Consideration |
|---|---|---|
| VEVOR Aluminum Underbody Box | Camper backs, racks, and flexible mounting locations | Check available mounting space and method |
| VEVOR Steel Tongue Box, Upgraded Lock | Trailer and RV storage | Steel construction; confirm fit before buying |
| VEVOR Steel Tongue Box | Weather-protected trailer storage | Designed as a tongue box, not a shell-specific box |
| CRAFTSMAN 16-Inch Tool Box | Portable hand-tool storage | Smaller capacity than mounted boxes |
| 14-Inch Gas Struts | Potentially compatible hatch-support replacement | Match dimensions and force requirements |
VEVOR Aluminum Underbody Truck Box

Best for: Buyers who want a lockable storage box that may be installed at the back of a camper or on a pickup rack. The listing specifically identifies those locations as possible uses, making this the most directly relevant option for some camper-shell setups.
The box measures 30 × 14 × 16 inches and is made from aluminum alloy with a tread-patterned panel. A rubber sealing strip is designed to help keep water out, and the box includes a lock and keys with a T-handle latch. Its stated corrosion resistance may be useful for equipment carried outdoors.
Limitation: The listing does not establish that the box fits every shell or specify a universal mounting method. Measure the available space and confirm how it can be secured before purchase.
VEVOR Steel Tongue Box With Upgraded Lock

Best for: Trailer or RV owners who need a larger weather-conscious storage chest for tools, batteries, or outdoor gear. Its 36 × 12 × 12-inch listed size makes it a better match for buyers with room for a long, narrow box than for those needing a compact portable case.
VEVOR describes this model as cold-rolled steel with protection against rust and wear. The overlapping door and extra-wide sealing strips are designed to help block water intrusion. The upgraded-lock version is intended for buyers who prioritize securing stored equipment.
Limitation: This is a trailer tongue box, not a camper-shell-specific product. Check dimensions, mounting location, and clearance before adapting it to a truck or shell.
VEVOR Steel Trailer Tongue Box

Best for: Buyers who want a 36-inch steel storage chest for trailer or RV equipment. It offers the same general storage format as the upgraded-lock VEVOR option and is worth comparing if the listed size and weather-resistant design meet your needs.
The box provides 36 × 12 × 12 inches of stated storage space for tools, batteries, and outdoor equipment. Its carbon-steel construction has a double-sided surface treatment intended to resist rust and wear. An overlapping door and wide sealing strip are designed to reduce water entry.
Limitation: The provided features do not specify an upgraded lock. As with any tongue box, verify that its shape and mounting requirements suit your intended location.
CRAFTSMAN 16-Inch Lockable Tool Box

Best for: Drivers who need a portable container for a smaller selection of hand tools rather than a permanently mounted chest. Its 16-inch format is easier to carry than the larger tongue boxes, making it a practical choice for tools that may move between a garage and truck.
The listed features include a padlock eye, front metal latch, and comfort-grip handle. Choose this if portability and basic tool organization matter more than maximizing storage volume or mounting a box to the shell.
Limitation: The supplied product details do not describe weather sealing. Avoid relying on it to keep contents dry in an exposed truck-bed location unless you confirm its protection needs are met.
14-Inch Gas Struts, Pair

Best for: A buyer searching for lift supports rather than a storage box, provided the measurements and force match the existing application. The package contains two struts rated at 24 pounds or 107 newtons each, with a stated compressed hole-to-hole length of 8.9 inches and extended length of 13.98 inches.
The seller says installation requires a flat screwdriver and no special tools. These supports may be relevant to a camper-shell hatch project, but the listing does not confirm compatibility with a particular shell or hatch.
Limitation: Do not choose struts by length alone. Compare the existing supports’ force, end fittings, and measurements before ordering.
Buying Guide: How to Choose a Camper Shell Tool Box
Where will the box go?
Start by deciding whether the box will sit inside the shell, attach at the rear, mount to a rack, or serve a trailer. A tongue box is designed for trailer use, while the VEVOR aluminum listing specifically mentions installation at the back of a camper or on a pickup rack. Neither description guarantees fit on every vehicle. Measure the space, including the opening path of doors and hatches.
How much storage do you need?
Compare interior capacity and the size of the objects you plan to carry. The two VEVOR steel tongue boxes list 36 × 12 × 12-inch dimensions, while the aluminum box lists exterior dimensions of 30 × 14 × 16 inches. A 16-inch portable tool box is better for a limited hand-tool selection than bulky equipment. Keep weight and access in mind as well as volume.
Does it need weather protection or a lock?
For gear exposed to rain, look for stated sealing features. The VEVOR boxes describe overlapping doors or rubber sealing strips intended to limit water intrusion. These details are not a guarantee of waterproof performance in every installation. For security, distinguish between a lock included with the product and a padlock eye that requires a separate padlock.
Will the mounting and hatch hardware fit?
Confirm the intended mounting surface and attachment method before buying a storage box. For gas struts, compare the old supports’ extended and compressed lengths, force rating, and fittings. The listed 14-inch pair should not be treated as a universal camper-shell replacement.
Frequently Asked Questions
Can a trailer tongue box be used on a camper shell?
Possibly, but the product listing does not confirm universal shell compatibility. Check dimensions, mounting points, access, and vehicle clearance before adapting one.
Which listed box is most directly suited to a camper setup?
The VEVOR aluminum underbody box is the most directly relevant because its listing mentions installation at the back of a camper or on a pickup rack.
Are the VEVOR steel boxes described as weather resistant?
Yes. Their listed overlapping doors and sealing strips are designed to help reduce water intrusion. The descriptions do not establish that either box is fully waterproof.
Are the gas struts tool boxes?
No. They are lift supports. Consider them only when replacing hatch supports and after checking the required dimensions and force.
