I am new to RVing and to having a class C. I just bought an 05 Thor 28 and I want to get it set up right. I live in southern Indiana not real close to any big city. Bought the unit at Camping World and through their inspections and services I have the RV part in good shape (I am satisfied). But now I want to be sure about shocks, brakes, steering, and engine diagnostics (as needed). Other than an oil change (which they did), I found out this has to be done by a garage. I asked my small town dealer and they don't work on anything bigger than an ambulance. Where to look? Should I look far and wide for dealers? Should I look at heavy truck places? This is a little frustrating, though the unit seems to run good right now, I want a starting point. Help......thanks!
