Look under the coach on the passenger side and just ahead of the outside of the tire. You'll see a very large bracket that is bolted to the frame at the top and has a large bolt at the bottom. You can see this without climbing underneath the coach. Look on the large bolt at the bottom and there will be a large washer under it (Everything is large under there). There is another washer on the inside. These washers must have some tack welds to the beam that runs front to rear and underneath the differential. I suspect the welds have failed or were removed by someone. This is where the adjustment for the thrust angle is located. Sounds a little Mickey Mouse I know but knowing that many large Class A's have no adjustment at all this is not too bad.
If this is your problem you will need to get it to someone that has the equipment to adjust the trust angle then place a couple of small welds between the washers and beam. Just tightening the large bolt will not hold the thrust adjustment by itself.
If pictures would help let me know.
