5.9 Magnum help needed

Well the bed as far as I remember has 4 bolts and the filler tube and can be slid back with one or two ppl.The tank you have to get under and remove the straps and probably the vent lines so I would say(since I worked at a place that removed truck beds) once you remove the bed it gets easier every time.And no they were not pulling your leg about the bed.But to be honest niether is a choice I want to make any time soon.
