I was running my tire pressure too high. My coach has fairly new tires all around and I had been keeping them up to the cold pressure marked on the sidewall. I found out through the forum that the pressure should be lower. Once I dropped about 20 lbs the entire rig smoothed out.
Part of the tire issue is that when these coaches were new, they had load range D's on them, over the years, the load range has gone up to E's, or even F's, which means the tire is capable of carrying more weight, and more air pressure. IIRC, the original tire pressure for these rigs was 65PSI.
Try the lower pressure, and see how it rides. You can always bump the pressure back up some if you notice rolling and swaying, until you get a ride you are happy with. If the shocks are not worn out or broken, you shouldn't have to replace them, although shock manufacturers recomend taking a look at them after 20K miles.
