So you answer this question, which puts more stress on the frame, towing at 3500 lbs for 200,000 miles, or towing at 4200 lbs for 1500 miles?
The answer apparently is that as soon as you pull out of the driveway a couple hundred lbs over the hitch rating, you have instant and massive failure of everything. It doesn't even matter if the poor guy has a re-enforced frame or not.
That thought process is silly. Metal fatigue happens over time. The extra weight is in no way close to actually bending something pulling out of a driveway, especially with no tongue weight. The load is tensile and compressive. There is a small amount of side to side stress that could be greater than the original design, however the side to side load would be prevented from excessive movement because of the coach flooring.
