For some reason I was thinking of putting a pair of 40# on the froy of my 98 StarCraft SpaceMaster and as expected they won't fit in factory place. I was thinking is there any reason I can't mount the 2 tanks tight to the front on the outside of the front? I have no problem rounding up metal or welding up something for them to sit in that's just under the tongue and have them low enough to clear the bed. They only have to be as low as the underside of the frame to fit but spread to the outside on each side.
