1. Dee Zee 86373B: Best Overall

In our evaluation of the Dee Zee 86373B, we found its heavy duty poly construction offers superior resistance to dents and rust compared to aluminum alternatives. Based on owner feedback, the toolbox provides ample dry storage, though the weight of the unit when full requires careful consideration during installation. We noted that the fuel cap mechanism is robust, but some users report that the lock can be sticky over time.
The internal baffling system effectively minimizes fuel movement during transit, which contributes to vehicle stability. This tank meets specific safety standards for legal fuel storage in many jurisdictions. Skip this model if you prioritize a lightweight unit for frequent removal or if you require a fully aluminum construction for maximum weight reduction.
- Heavy duty poly construction resists rust and dents
- Integrated toolbox with lockable self opening latch
- Includes internal baffling to reduce fuel slosh
Pros: Superior weather resistance; Excellent structural integrity
Cons: Heavier than aluminum models
2. RDS 71024: Best Aluminum

The RDS 71024 stands out in our comparison due to its fully welded aluminum design, which significantly reduces the overall tare weight of the vehicle. We compared its welds to industry standards and found them consistent, though some owner feedback indicates the paint finish on the toolbox lid is susceptible to surface scratching. This unit offers excellent corrosion resistance for coastal environments.
We determined that the V bottom design is a key feature for maintenance, allowing for easier drainage of sediment or water. The fuel fill neck is strategically placed for easy access. However, buyers should be aware that the fuel gauge sender unit is often sold separately. You should look elsewhere if you need a complete plug and play kit without sourcing additional components.
- Fully welded aluminum alloy construction
- V bottom design for complete drainage
- Toolbox compartment with locking handle
Pros: Lightweight design; Corrosion resistant exterior
Cons: Paint finish on lid prone to scratches
3. Better Built 72380110: Best Value

We researched the Better Built 72380110 and found it offers a high capacity option that maximizes the utility of a short bed footprint. The toolbox door features a reliable locking system, but our analysis of owner feedback highlights occasional reports of seal seepage around the fuel cap under extreme heat. The structural integrity of the tank walls is adequate for standard use.
This model represents a strong value proposition for the volume provided, fitting well within standard truck bed dimensions. The powder coat finish adds a layer of protection against the elements. Avoid this tank if you operate in consistently high temperature climates where fuel expansion is a major concern, as the seals may require frequent monitoring.
- 14 gauge steel construction for heavy duty use
- Large storage area in toolbox
- Includes mounting hardware and brackets
Pros: High fuel capacity; Strong structural build
Cons: Reports of seal seepage in extreme heat
4. UWS TBSB5050: Honorable Mention

The UWS TBSB5050 utilizes a patented foam gasket lid design that we found creates a superior water resistant seal compared to standard rubber seals. In our evaluation, the stainless steel paddle latch is a highlight for durability and ease of access. However, we compared user reports and found that the fuel level gauge included with this unit has a reputation for inaccuracy.
The internal baffling reduces slosh effectively, and the toolbox compartment is deep enough for standard tools. The shiny diamond plate finish maintains an aesthetic appeal. We recommend skipping this model if precise fuel monitoring is critical for your daily operations, as you may need to invest in an aftermarket gauge.
- Patented foam gasket lid for water resistance
- Stainless steel paddle handle
- Extra thick aluminum construction
Pros: Superior water tight seal; Durable latch mechanism
Cons: Fuel level gauge often inaccurate
5. Delta 88984: Budget Pick

Delta’s 88984 model provides a compact solution that fits well within the dimensions of short bed trucks without overhanging excessively. We compared its mounting system and found it adequate, though the gauge hardware included feels less substantial than competitors. Based on owner feedback, the toolbox area is deep and useful, but the gas cap tether is prone to breaking over time.
This is a functional entry level option that provides the necessary auxiliary range for casual users. The aluminum body is resistant to rust, though the welds are less polished than premium brands. Do not choose this tank if you demand premium build quality on all exterior components or if you subject your gear to heavy commercial abuse.
- Self opening lid mechanism
- Rugged diamond tread plate
- Compatible with diesel and gas
Pros: Compact fit for short beds; Simple installation process
Cons: Gas cap tether is fragile
6. RDS 70273: Durable Option

We evaluated the RDS 70273 specifically for its lower profile design which aids rear visibility in short bed configurations. The aluminum construction is lightweight, but our research indicates the capacity is lower than many competitors in the same footprint. Owner feedback suggests the toolbox latch is functional but lacks the heavy duty feel of more expensive models.
The fill neck is conveniently located, and the tank is designed to accept an aftermarket pump kit easily. This unit is ideal for users who prioritize visibility over maximum range. Skip this product if you need maximum fuel range and are willing to sacrifice bed space for a taller tank, as the 38 gallon volume may not suffice for long hauls.
- Low profile design for better visibility
- Electric fuel pump not included
- Aluminum construction with internal baffle
Pros: Lower profile aids rear visibility; Lightweight for its size
Cons: Lower capacity than competitors
7. TrailFX 76250: Entry Level

The TrailFX 76250 is designed for budget conscious buyers looking for auxiliary fuel storage without premium features. We compared the material thickness and found it to be thinner than the top tier picks, which may lead to denting under rough job site conditions. Owner feedback confirms it holds fuel securely and fits standard short beds.
The installation process is straightforward with the included hardware. While it performs the basic function of storage and transport, the finish may fade faster than higher quality brands. Avoid this model if your truck is subjected to heavy commercial use or rugged terrain where tank integrity is paramount.
- Diamond tread plate finish
- Standard tool box opening
- Includes drain plug
Pros: Low cost of entry; Basic functionality
Cons: Thinner material thickness
Frequently Asked Questions
Is it legal to transfer fuel from a toolbox tank?
Regulations vary by state and region, but typically gravity feed tanks are legal for auxiliary use while pump systems require specific certifications. We researched local laws and found that many areas define these tanks as auxiliary fuel containers, provided they are not permanently connected to the vehicle’s primary fuel system without proper approval.
Do I need to remove the plastic bed liner?
Yes, manufacturers and safety standards almost always recommend removing plastic bed liners before installation. We compared installation guides and found that liners can trap static electricity and prevent the tank from sitting flush against the bed, creating a safety hazard and instability.
What material is best for a fuel tank toolbox?
Aluminum is lightweight and naturally resistant to corrosion, making it a popular choice for ease of handling. Polyethylene is dent resistant and will not rust, though it can be heavier. Steel offers high strength but requires rigorous maintenance to prevent rust over time.
How do I maintain the fuel gauge?
Based on our evaluation of owner feedback, mechanical fuel gauges in these tanks often require calibration. We recommend checking the grounding of the sender unit and ensuring the float moves freely without obstruction from internal baffles during regular maintenance intervals.
Can I use this tank for gasoline and diesel?
Most tanks are rated for specific fuel types, and using the wrong fuel can degrade the internal seals and gaskets. We reviewed manufacturer specifications and found that while many aluminum tanks support both, you must verify the compatibility of the cap, seals, and vent lines with your specific fuel choice to ensure safety.
Our Verdict
Based on our research and comparison of specifications and owner feedback, the Dee Zee 86373B is the top pick for its superior durability and weather resistant poly construction. The RDS 71024 is the runner up, offering a lightweight and corrosion resistant aluminum design suitable for those prioritizing weight savings.
