well... i don't think it will work, i took the measurements and it doesn't fit accross. 39 3/8" it will actually hit the leaf suspension. it would of clear if it was closer to 38. also if i make the tank parallel to the floor it will clear the floor by around 6"-7" is it the same on yours? but atleast i have a better idea on tanks and not just look for one that will fit between the rails.
