The service department is amazing!
The service department is amazing! I’ve been an RV owner for years & I’ve never had a better experience. I had my hydraulic jacks repaired, entertainment center completely rewired, & backup camera wired all in 2 days & for 1/3 the price I was quoted just for the parts for the jacks at another dealership.
