RCD to the Rescue!
We had a major issue with our new Winnebago TT which was purchased somewhere else. After picking up at RCD for for warranty work, 2 stabilizers broke loose while merging onto the interstate. RCD sent Buck out who repaired us on the spot! Thank heaven for the great team at RCD!

Missie from Zanesville, OH
Wife's in love with it
As with the headline, its mainly my wife's baby. So far she absolutely loves it. From my vantage point its a very good camper with a lot of great amenities that make camping enjoyable.

Kenneth
Very happy
I was very happy with the experience at Avalon. Winn was our salesman and he worked with us and got us everything we were promised was very knowledgable about our RV. Mark in finance was very professional and nice. Jeff and Matt in service explained everything about our RV really well and worked great
