This is the opinion from an AF 1140 owner......don't try it with a SRW truck. The 1140 is one of the heaviest campers out there, and too much for a SRW truck. As far as construction, the AF is very well built. Back in the early 2000's they did have some issues with delamination. From what I can tell that problem area was addressed around 2008 or there abouts. Make sure to check for wall delmaination. Also pay attention around the front markers lights as the old style (incandescent) ones had a tendency to take in water. Once they got so much water inside it would work its way back thru the wire access hole and into the wall of the camper.
