A General Where-to-Service Question

Over the years with various gas motorhomes we've had an engine, a transmission, and a complete rear end replaced, as well as several other more minor drive line repairs. In almost every case, we've had the work done at an independent truck shop, usually one recommended by our emergency roadside service provider, and have always felt we were treated fairly. We do have a Ford dealer near our upstate NY get away cottage that does a lot of RV work, and even has a large building specially built for RV body work and painting. We've only used them once for some A/C work and a brake switch recall though. Most of the other lesser issues with the drive line, electrical, appliances, etc., I handle myself, but I wouldn't hesitate to call a mobile RV tech if I was stumped by something.
