I am getting a few things fixed up on my 2004 Beaver Monterey. Currently working with Cummins but do not feel they are up to the task really. Friendly but pricey and not up to speed on the coach and systems. Looking for service on Cruise Control, possibly Exhaust Brake, etc as well as Body/Interior things and electrical. Any good shops for engine and Chassis...etc. Any assistance greatly appreciated. Ed
