If you want to see what the MFGs response to poor quality in the RV business is all about just look at Grand Design. When they started the company they, (3 guys from Keystone) knew they couldn't build the perfect RV. So even though they may build one that's better than some they still knew that their trailers would still need warranty work. So they came up with a solution. Offer the best customer service possible. Seems to be working, although I think they're getting a bit inundated with a lot of warranty work. Happens when you start producing more models and more units all the while still dealing with problematic parts.
It's too bad that they couldn't of decided to build the perfect trailer but they probably knew that they would price themselves out of the market.
