A year ago I took my coach to a local truck service company, Eagle Freightliner. The company works on all species of trucks, transmissions, etc., changed all my oils and filters, and serviced my Onan generator. I left the coach there for several days where it was parked in a bay out of the sun. My alternative was to take it to one of several RV sales/service companies 35 miles away, or take it to Bend 215 miles away. Eagle Freightliner has a couple truck shops on I84 within 100 miles of me here in NE Oregon. The shop I went to is only 5 miles away from my home.
Had I needed service on something unique to my RV, then I would likely take it to Bend... which I have done for slide work.
