We've only had two RV's. Our Fifth Wheel was an Alumiscape. The Factory wass excellent on the couple of repairs we needed and on assistance and replacing a couple of things that broke on the road.
Our Fleetwood/American Coach RV had a lot of problems becaause Dealer messed it up and so on and then they wrecked it. The Factory went out of their way to help us with it. We spent as many as three times a year at the factory. it is finally just about solid.
I think the next coach will be an American Coach. They have changed hands and be reorganized but many of the same talented and committed people are still with them.
