I have owned two older Newells and I have not had problems finding parts, but I have seen posts here where owners of certain basement A/C units were unable to locate parts. I have always taken the approach that when something fails it is the perfect opportunity to upgrade to later technology. This works well with TVs, radios, microwaves, furnaces, refrigerators, inverters, chargers, etc.

Finding someone capable of working on a Newell Coach would require due diligence on your side. Your running gear is comparable to over the road trucks and buses so you would look for shops that work on similar equipment. I prefer independents with good reputations to the dealerships but that's just me. As far as other repairs that you may need you'll need to use common sense to determine who you should go to.
