Extended range

Looking for some ideas to extend the driving range of my Tacoma. Mostly looking for ideas on fuel tanks, such as either an extra tank or a larger capacity tank. My endstate goal is to extend the range by about 300 miles on the highway, so, I'm looking to hold about an extra 15-20 gals of fuel, fuel that I don't have to get out of my truck to use (I want jerry cans to be for emergency use only, etc). Suggestions?

 

add a fuel cell in the bed and then add plumbing to your tank...?maybe?

 

problem solved - put 3, 5 gallon gas can in the bed of the truck then just bring a passenger to climb out the window into the bed and lean over the side of the bed and fill her up! thats what i would do anyway.

j/k, good luck finding a solution.
