You might be looking in the wrong place for wear. Never had a problem with receiver wear but have seen two hitches rip from the frame rails on motorhomes over time. On one the frame had sections around the attaching bolts break out and the other had the sections of the hitch crack and break loose. In both occurrences the hitch was pivoting by only the forward most bolts and they were close to total separation. Both of these hitches flat bolted up to the bottom of the frame rails with no side supports. The safety chains and break-away cables are only attached to the hitch and the hitch and trailer would have drifted away from the tow vehicle unimpeded. I suspect that the 6" drop hitches probably added a lot of leverage that helped with the metal fatigue.
Truck manufacturers are better at taking into account that large loads will be towed, but motorhome manufacturers don't realize that many of us are towing a lot of weight behind us.
