SOLVED. After a few thousand miles of white knuckle driving I have finally solved this drivability nightmare. Driving stress level has gone from nine to one by making just a few changes.
Thank you so much to all that responded and changed my focus from steering geometry to tire pressure. Following the sticker behind the drivers seat, the front tires were at 115 and the rear were at 95. After weighing the loaded coach, all six tires are now at 85 PSI. Pot holes that felt like a bomb going off are now just a mild thump, and the higher frequency road noise that was transferred right into the chassis and kept everything rattling is now completely gone. It’s a completely new driving experience, and a much more relaxing ride.
But here’s the one that we all missed. Even the experts missed it when I took the coach into the alignment shop the first time. The steering problem was because the coach was dog tracking down the road. The rear wheels were not following the same center line as the front wheels, and while driving I was constantly trying to correct that misalignment. Always trying to line the front with the rear, and of course I was never able to do it. A constant fight was going on in the background as I drove down the highway. I was beginning to think I couldn’t keep the rig between the lines because the right rear set would sometimes run off the asphalt on narrow roads. The alignment guy loosened all of the bolts holding the rear axle and put a porta-power against the frame to push things into alignment. This adjustment has made a huge difference in the way this rig rolls down the highway, and now finally, I CAN look away.
