Mike, if you make sure you're logged in, go to the Home tab above, then choose "Private BAC Members Only" from the General Boards list, then "Service Provider Guide", and click the "RV Service Providers Guide" link on Steve's note, it will download a pdf you can open. There are many shops listed under Arizona, and you can see whether members here had good or bad experiences and how long ago. Others of those here may respond directly to your query.
That said, it is uncommon that a coach with so few miles on it should need either bags or shocks. The exception would be had they been damaged in some way. Personal experience, myself and others here, would deem the recommendation of Henderson's Line Up in Grants Pass, Oregon. They are the go-to experts with anything motorhome chassis, and BAC sponsors. It's probably not likely that you'd want to go that far by the sound of it, so hopefully other options will be provided here. Henderson's (and I) would go with Koni shocks, assuming you don't already have them, not so much as because yours have worn out, but rather as an upgrade. I noticed the difference when I changed from the factory ones (Bilsteins?), but I also added other Henderson services and products that contributed to a much improved ride and handling.
