Seriously considering a JeepSpeed Jaz Fuel cell before I do this axle swap. Reasoning behind this is two main reasons:
1) It isn't as wide as the F150 tank I have now. I want to push my axle back another 3-4" so I get a longer wheelbase, better departure angle and most importantly more clearance for up travel with longer shocks and bigger tires. Right now I have my axle pushed back as far as I can without hitting the axle on the crossmember/fuel tank at full bump. I'd like to keep the same up travel but right now I have already tubbed as much as possible with 35's and 12" shocks and I am already into the rear door and seats as my limiting factor. Only place to go now is back more (already pushed the axle 3" back.)
2) More capacity. With the F150 tank it is only an 18 gallon tank so capacity is pretty limited, but also due to the flat, wide shape of the tank the actual usable fuel capacity is limited to like 14 gallons before it starts starving for fuel in hard turns or steep hills which is super sketchy if I lose engine power (losing power brakes) on a hill with my family. I have to take spare fuel with me on trips which is just a pain in the ass, so might as well go with higher capacity and not have a 5 gallon fuel tank sitting in the back of the truck.
I think this is the best of both options of more clearance and more capacity that I am looking for. I'm always looking for used parts so if anyone knows someone getting rid of a Jaz JeepSpeed fuel cell let me know.

I may just buy this TMR mount or make my own.
