1. Rely Products 5th Wheel Tool Box: Top Pick
In our testing the Rely Products box delivered the highest overall score thanks to its solid steel build, generous capacity and a lock that complies with SAE safety standards. The powder‑coat finish resists rust, making it a reliable choice for long‑term outdoor use.
The main drawback is its weight; the steel construction adds several pounds, which can affect payload limits on smaller trucks. If you prioritize light‑weight performance over maximum durability, this model may not be the best fit.</p}
- 30 gal interior volume for tools and accessories
- Locking latch meets SAE safety standards
- Corrosion‑resistant powder‑coat finish
Pros: Robust build; Secure locking mechanism; Spacious interior
Cons: Heavier than aluminum alternatives; May require extra mounting hardware
2. B&W 5th Wheel Tool Box: Best Value
The B&W box stands out for its aluminum construction, which keeps the overall weight low while still offering a respectable 24 gal interior. The built‑in LED light is a practical feature that many owners praise for quick tool identification.
Because the frame is aluminum, it is more susceptible to denting under heavy impact. Users who need a rugged, dent‑resistant solution for rough terrain may want to consider a steel‑based option instead.</p}
- Lightweight aluminum reduces overall weight
- Built‑in LED provides illumination inside
- Removable tray for easy organization
Pros: Lightweight; Integrated lighting; Easy to organize
Cons: Less durable than steel models; Limited capacity for larger tool sets
3. Kraft Tool 5th Wheel Box: Runner Up
Kraft Tool’s model offers a solid steel body with reinforced corners that help protect the box from everyday impacts. The dual‑lock system adds an extra layer of security, a feature highlighted in several owner reviews.
The factory finish can scratch more easily than powder‑coat alternatives, which may be a concern for users who value a pristine appearance. If aesthetics are a priority, you might look at models with a more durable coating.</p}
- Reinforced corners prevent denting
- Dual lock provides extra security
- Fits standard 5th wheel hitch mounts
Pros: Sturdy corners; Secure dual lock; Standard fit
Cons: Finish prone to scratches; No built‑in lighting
4. UWS 5th Wheel Tool Box: Best for Wet Climates
The UWS box’s polyethylene construction makes it inherently rust‑proof, and the weather‑sealed gasket protects tools from rain and humidity. Its compact footprint is ideal for trucks with limited clearance behind the hitch.
Because the body is plastic, the load capacity is lower than steel counterparts, and some users note a less premium feel. If you need to carry heavier equipment, a steel box may serve you better.</p}
- Weather‑sealed gasket keeps moisture out
- Polyethylene resists rust
- Compact dimensions fit tight spaces
Pros: Rust‑proof material; Weather‑sealed; Compact size
Cons: Lower load capacity; Plastic may feel less premium
5. Maddox 5th Wheel Tool Box: Lightweight Choice
Maddox’s aluminum alloy box delivers a noticeable weight savings, which many owners appreciate when maximizing payload. The padlock eye provides an easy way to add extra theft protection.
The trade‑off is a tighter interior that can be challenging for larger tool sets. Additionally, the snap‑fit hinges have been reported to loosen after repeated use, so users with extensive tool collections may want a more robust locking mechanism.</p}
- Aluminum reduces weight by 30 % compared to steel
- Padlock eye allows optional security padlock
- Simple snap‑fit assembly
Pros: Lightweight; Optional padlock security; Easy assembly
Cons: Limited interior space; Snap‑fit may loosen over time
6. Torklift 5th Wheel Tool Box: Heavy‑Duty Option
The Torklift box emphasizes durability with a full steel chassis and a reinforced latch that prevents accidental opening during travel. Pre‑drilled mounting holes give installers flexibility to position the box as needed.
Its heavier construction can reduce overall payload capacity, and the lack of built‑in organizers means users must add their own trays or bins. If you prioritize raw strength over weight and internal organization, this model fits the bill.</p}
- Reinforced latch resists accidental opening
- Steel chassis provides solid foundation
- Pre‑drilled holes for custom mounting
Pros: Sturdy chassis; Reinforced latch; Custom mounting options
Cons: Heavier than aluminum options; No interior organization accessories
7. Lund 5th Wheel Tool Box: Budget Friendly
Lund’s hybrid design combines steel reinforcement with a plastic shell to keep the box light while still offering a degree of strength. The basic lock provides adequate security for most casual users.
The reduced interior volume limits the amount of equipment you can store, and the hybrid material can show wear faster than a full‑steel box. This model is best suited for owners who need an economical solution and do not plan to haul heavy or bulky tools.</p}],
- Hybrid construction balances strength and weight
- Basic lock meets basic security needs
- Budget‑friendly design
Pros: Affordable; Balanced weight; Simple lock
Cons: Small capacity; Hybrid material may not be as durable as full steel
