Nearly impossible to get Class C Chassis serviced?

Try Best Auto and Motorhome. 303-422-7304. Talk to Jack. We had a decent experience there about 4 years ago. Yes, it is very hard to find a good shop for older RV's. Expect problems at any shop you find and try to plan ahead. I wind up doing a lot of mechanical work myself. After having to drop my gas tank 4 times I replaced all the fuel lines and went with an external fuel pump. One of the better decisions that I have made.
