Oops...sorry I forgot to add to my previous post, that we went with the HD shocks. I heard the same thing about break-in time though, but we don't really find these to be too rough at all right now. If they get even better I'll be even happier with them. As I said before, I wouldn't own another Class C coach without Bilstein shocks.
I've been trying to order a Roadmaster RSS unit for the new coach, but they are all sold out right now. You can find the bracket kit, but not the steering stabilizer unit itself. Looks like a 3-4 week wait, according to the Amazon.com documentation, and the fellow I spoke with at HitchSource.com (where I ordered my Equinox baseplate).
Good thing we aren't planning any long trips any time soon...
