Purchase
James is excellent. Found the RV we were looking for in stock. Great communication throughout process. Roger, the coordinator, called the day before to confirm our appointment. Great experience with this dealership.

Scott from Surprise, AZ
Great Customer service
What we liked about this dealership was the personal attentiveness by Rob A. Detailed instructions on how to operate the trailer. We appreciate their wIllingness to accommodate changes in appointment schedule especially since we were coming from out of town. They were recommended by a family member

Herman from Albuquerque, NM
Top Notch Service
The people at the Mesa location are the best. We just purchased our 2nd trailer and wouldn’t have gone anywhere else. I called Carol and said here is what we want, how soon can you get one here for us? She made it happen and kept us informed along the way. Once the trailer arrived Dreu walked us through
