I do remember seeing one RV owner who seemed to exceed his tow limits a few years back. It was in the UP of Mich. and he had just gone o ver a dip in the pavement. He had literally broken the back of his MH and it was sitting on the side of the road with the rear end dragging on the pavement and the fiberglass cracked from the wheel up to the roof. That would be one way to total a MH. and probably not get any insurance coverage. In my first MH, a '76 Fireball that was 21'long there was no frame suitable to attach a trailer hitch so I could not tow anything. Many time you will find that a Manuf. will change the specs on a frame from one year to the next. Not all P30s are necessarily the same.
