Over the Bed Fuelbox

The Over the Bed Fuelbox OBFB70 tank is constructed of high-quality .125 marine grade aluminum and has a heavy-duty lid constructed of .100 marine grade aluminum with extra large lid stiffener. The auxiliary tank has true flange weld seam design, which doubles weld joint thickness for stronger welds. It has full lid length continuous hinge, also stainless steel latch and lock assemblies.  The tank has a minimum of 2 interior baffles. The toolbox has a unique rain channel with the neoprene on the lid that assures a weather tight seal. You will also find that the bottom of the toolbox is not the top of the fuel tank, adding extra strength and protection to the fuel tank. This box is adjustable to fit all truck bed heights. 

The Fuelbox is a universal product that can be used as an auxiliary, transfer tank, or both. There are many options for you to outfit your Fuelbox to fit your exact needs. All options are priced separately so you have the freedom to choose how you want to use your Fuelbox.
