Extra fuel tank
I have a 100 gal. fuel tank/tool box combo and love it. The ability to load up with cheep fuel has saved enough to pay for the fuel tank several times over. The only down side is that you have to pay to haul that extra fuel around. My tank weighs 150-200 lbs and the fuel around 800 lbs so I am looking at 1k # extra weight and that equals about 1 mpg to haul the 100 gal of fuel.
Note: With a bed mounted fuel tank it is easy to mount a 2 micron fuel filter under the bed and let the fuel gravity drain from the tank and into the OEM tank.
