Re: Best RV for Winter living The manufactures that I have named that closed their doors are some of the big top of the line names in the 5th Wheel industry. I think it has to do with the economy being in the tank and the top of the line RV's being very expensive. I previously mentioned that lately I have heard a few negative stories in the campgrounds about Keystone products. Keystone manufacturers Montana/Cougar. It may be just sloppy quality control practices or new young workers. Actually I don't think any of the manufacturers including NUWA--HitchHiker are up to the standards of a few years ago. I would still consider a Keystone product, but would really inspect the RV before taking ownership.
