Vigorighter 51 Gallon Aluminum Fuel Tank With Toolbox

The Vigorighter model combines a 51-gallon aluminum fuel tank with a built-in toolbox, designed for space efficiency in a truck bed. The aluminum construction contributes to corrosion resistance and durability in harsh environments. A 12 GPM transfer pump, 13-foot hose, and auto nozzle enable spill-free fueling in the field. This unit is best for transport teams and contractors who need to consolidate refueling and tool storage into a single, portable setup. A potential limitation is the overall footprint; while compact, it still occupies substantial bed space for buyers who haul large cargo alongside fuel.
DEE ZEE DZ92556NSB Transfer Tank

This model uses heavy-duty 14-gauge steel with a radius curve to reduce weld stress and includes five stability baffles and a drain plug. The steel construction emphasizes durability under heavy use, making it suitable for fleets or trades that encounter rough job sites. Best for buyers who prioritize rugged steel strength over lightweight aluminum, though the heavier material may affect handling and installation.
DEE ZEE DZ92647B Black 92 Gallon Aluminum Combo

This black aluminum combo pairs a large tank with integrated storage, finished in a protective powder coat. The aluminum build offers corrosion resistance and lighter weight compared to steel, aiding ease of installation in tight bed spaces. Best for buyers who want a large capacity with added toolbox storage while keeping weight manageable. A limitation is that aluminum, while corrosion resistant, may require careful maintenance to prevent dents that could affect seals over time.
RDS MFG INC Fuel Tank – 60-Gallon

The 60-gallon tank from RDS MFG INC emphasizes versatility, with options to fit various short-bed configurations. It supports external fueling via electric pump and notes compatibility with certain bed dimensions. Best for buyers who need a flexible fit across different trucks and bed sizes. Caution: measure your bed before ordering to ensure fitment, as some short-bed models may not align perfectly with all frames.
Better Built 36-Gallon Steel Transfer Tank

This steel transfer tank offers a 36-gallon capacity with an automatic shutoff to prevent spills and built-in baffles to stabilize contents during transport. It’s a solid, straightforward option for buyers who need dependable fuel transfer without extra toolbox features. Choose this if you prioritize spill prevention and robust steel construction for severe work sites. Limitation: smaller capacity than some aluminum or larger steel models, which may require more frequent refueling on long jobs.
Aluminum Rectangular 45 Gallon Tank By STMGW

This 45-gallon aluminum rectangular tank focuses on space efficiency with dimensions suited for multiple mounting configurations. Aluminum construction enhances corrosion resistance and reduces overall weight for easier handling during installation. Best for buyers who need a compact, lightweight option that still delivers solid capacity. Potential consideration: length and mounting points should be verified to ensure compatibility with your vehicle’s bed layout.
RDS MFG INC 60 Gallon – Toolbox Combo

This 60-gallon toolbox combo from RDS MFG INC combines generous fuel capacity with added storage, designed for organized, efficient on-site work. Best for buyers who want both storage and fuel in a single unit, minimizing separate cargo space usage. Limitation: the package dimensions and mounting requirements should be checked to ensure proper fitment on your truck bed.
RDS MFG INC 69 Gallon Rectangular Tank

The 69-gallon rectangular auxiliary tank from RDS MFG INC emphasizes space-efficient mounting with a generous capacity. It’s suitable for buyers who need a larger fuel reserve without sprawling over the bed. Best for those who want a balance between capacity and bed space, though installation guidance should be consulted to confirm fit with your vehicle. Caution: ensure top-filling compatibility if you plan to siphon or pump from the top end.
Buying Guide: How To Choose The Right Fuel Tank Truck Bed
- Capacity vs. bed space: Larger tanks increase available fuel but reduce usable bed area. Measure your truck bed and compare to tank dimensions before buying.
- Material choice: Aluminum is lighter and corrosion-resistant; steel offers ultimate durability and stability on rough sites. Consider your typical environment and corrosion exposure.
- Mounting and fit: Some tanks are designed for short beds; others fit broader configurations. Check dimensions, bolt patterns, and installation requirements.
- Integrated features: Toolboxes, baffles, and spill-prevention systems add value for on-site use. Decide which features matter most for your workflow.
- Pump and hose setup: Built-in or external pumps affect ease of use and maintenance. Look for durable fittings and hoses with sufficient length for your operation.
