Buying Guide
What capacity should I choose?
- Choose larger tanks (50+ gallons) for long trips or jobs with minimal access to fueling, prioritizing fewer refuels.
- Smaller tanks (20–40 gallons) suit shorter tasks, urban use, or trucks with limited bed space.
Do I need a built-in toolbox?
- Built-in storage saves bed space and keeps tools organized, ideal for fleets and remote jobsites.
- Consider the toolbox size and whether it compromises fuel capacity or access to the tank.
What materials matter?
- Aluminum offers corrosion resistance and lighter weight, beneficial for high-mileage or off-road work.
- High-density polyethylene (HDPE) can be UV-resistant and impact-tolerant for portable tanks.
What about mounting and legality?
- Ensure mounting brackets fit your truck bed and frame rails securely to avoid movement and leaks.
- DOT approvals and permitted fuel types vary by model; verify legal use for your fuel type and region.
FAQ
- What is the best fuel tank for long trips? A larger capacity model like the 51-gallon Vigorighter option can reduce refueling frequency on extended trips.
- Can I use any tank with diesel or kerosene? Some tanks are designed for multiple fluids; check the product’s allowed fuels and DOT status before filling with non-gasoline fuels.
- Are portable tanks easier to move? Portable tanks like the Scepter Flo ’N Go offer maneuverability with wheels, suitable for varied terrains.
- Is aluminum better than steel for truck beds? Aluminum resists corrosion and is lighter, which helps payload and bed life, though steel can be durable in some designs.
- Do these tanks require professional installation? Installation complexity varies; some units are plug-and-play, while others need mounting brackets and seals.
- Will a toolbox reduce fuel capacity? Some combined units trade a portion of bed space for storage; measure your bed and fuel needs to balance both.
