thanks, steve, I called AERO TANKS and yes, they do make a 56 gal tank for my truck, (transferflow does NOT) but I would have to drive to commiefornia (californicatya), a two day round trip, to get their 180. 00 install,or pay the 370. 00 truck ship delivery ( I think they go by way of hawaii) or use a mercedes limo to deliver, either way,I like the price of the tank (approx 750$) but wont pay the extortion money. the place is NEXT TO nevada, not new york. altho, when I DO go to cal, I feel as if I left the USA.
