I needed to have a trailer brake repaired while traveling east to Wall, SD. I called ahead to the Sleepy Hollow RV Park for the location of a repair facility. The CG owner sent me to I-90 RV & Auto in Rapid City, SD (the Flying J exit). I called them to see if I could get the necessary work done today. They told be to come in. When I arrived I told them what I needed fixed, and they started on the job immediately. I was back on the road in 30 minutes, and the charge was reasonable. It was a very friendly dealer and service department, but not a Heartland dealer. However, it did not matter that I did not purchase from them or they did not carry my unit. They fixed what needed to be fixed. It is a good dealer to remember should you need work while in the Rapid City, SD area.
