I replaced my 2-20gal tanks with a single 40 gal tank. I am running longer rear leaf springs and the front spring hanger had to be moved forward. It would have worked with 16gal tanks but not my 2-20gal. You can do a 25gal or 31gal suburban/K5 tank even easier than the 40gal (I think), the 40gal tank is a tight fit even with a long bed.
