I'd prefer an in-frame rail tank. people drive way to crazy these days. I'll check them out. I have the provision for a spare, and a spare rim, but being a dually, if I need I can always rob a wheel and get home. No heavy loads on this ol gal. Her working days are over. Longer trips may just put a spare tire in the bed, just in case. Going to have to investigate that a little more. I really don't mind the in-cab tank, but I do mind the capacity because I have a 34 gallon tank on my daily driver truck and really dislike going to get fuel.
