3g T4R guys swap an early 90’s f150 tank in the spare tire location, fits between the frame rails nicely. I’ve considered that for an aux tank, lots of write ups on that one.

Somebody here put a 36 gal tank from a suburban in the same location, can’t remember who but there’s a write up on it. Gets like 800 mile range lol

edit: here’s the suburban tank write up

Thank you both for this information. I appreciate it.
