Janice, check with
American RV in Albuquerque. Found one good review for them at
www.rvservicereviews.com. The others in Albuquerque did not score well.
Also, you can do an inquiry at
www.rv.net.
When you get to the RV Park, (or better yet, call ahead and ask) you can inquire at the desk about a reliable mobile RV Tech. They should know the best (and worst).
