Chinook Glacier - Are They A Maintenance Problem?

[MTBob]

As long time Truck Camper owners, we are now considering upgrading to a Class C RV. It seems one of the better built B+/C class RV's is the Chinook Glacier. However,apparently this company stopped production in 2005. So, the "newest" is 12 years old. The Chinook Glacier appears to be loaded with all kinds of "nifty" features (read, hydraulic / electric / electronic systems) that add to the comfort and utility of the RV.
The current used 2004-2005 Glaciers are selling roughly in the $40-55,000 range, a high price for a class C that old.
If all the features of the camper work OK and require little maintenance, then perhaps this model camper is worth the price.
I'd like to know what you'all think about this camper and whether this vintage of camper is relatively maintenance free. Specifically, what component of the RV fails and can replacement parts be found?

The Chinook Glacier is built on the E450 Ford chassis. Parts are readily available and service is available at any Ford dealership that services Ford trucks. Most coach appliances, air conditioners, furnaces, etc. are standard equipment found on most class C motorhomes. The hydraulic level system and slide out are HWH with service available at the HWH factory as well as many RV service centers. However, the slide out is a pneumatic sealed slide and is a very top end slide out. The slide out bladder seal when needing replacement is very expensive. The electrical system is top of the line with features not found on most class C motorhomes. Some parts are no longer made by the original supplier but are available from other suppliers. Because of the complexity and luxury, they will have more maintenance than the average class C motorhome. What is not there cannot break. Whether they are worth it is a judgement call.
