Thanks Smitty! As I posted earlier, the coach doesn't seem to have any wag or steering problems, just a lot (well, a lot to me anyway) of body roll on uneven pavement. Tractor trailers passing me didn't even phase the coach and it steers very true and tight. I'm going to try to the inexpensive way of fixing that sway, as described in the link above to the McKinley Fix (also called the Cheap Handling Fix). When I do it, I'm also going to replace my rubber OEM sway bar bushings with the poly bushings to get even more stability. All totaled, I'll be in it for less than $100 and about an hour worth of driveway work on my back under the coach. If that doesn't fix it, then I'll go deeper, one component at a time....probably starting with shocks.
