Who ever built it did some good work but it has alot of dead space (In my opinion if you have a flat bed it should be total utility). There is a nice flat bed running around up here that has sides that expand out to fit two sleds and has a alum fuel cell under the deck and in between the frame rails close to the cab with a hand pump. He has the ramp telescope in two spots instead of one so when collapsed he fits it inbetween the frame rails under the deck behind the fuel cell. He has boxes under neath to fit gear on each side. This is all on a early 90's 1 ton Dodge Cummins. It is pretty much the best tow rig I have ever seen, he said its only purpose in life was to go riding.
