Keystone, forest river, jayco, thoughts on reliability?

Well, since you live in Oregon, why not consider an Oregon made trailer?
IMO the Northwood MFG Trailers (Arctic Fox) and Outdoor RV MFG (Wind River, Creekside, etc) are some of the best. Of course they do cost a bit more. Both are made over in La Grande.
I personally have a Jayco and feel it offers good value, but having looked at a lot of brands, I can see it is not as well built as the ones I mentioned above.
