Alright guys I'm going to have a fuel cell built problem is I dont know what exactly I want. I want it mounted under the bed floor, I cant put it in the back behind the axle as my exhaust is in the way, I could put it above the frame, just not between the rails. I plan on raising the floor about 3-4". Ideas? pretty much have to put it either in front of or behind the axle between the rails on top of the frame but under the raised floor.
