Welcome to the world of RVs. Ask any salesman: "Is the first question you get from a prospective customer on quality or price?". They are supplying what the market is asking for.
One thing to remember on an internet forum: quality is subjective, everyone is going to have a different assessment, even of exactly the same product. Good for one, bad for another - it just depends on your expectations. I keep my expectations in the RV world very, very low, and I am occasionally surprised on the upside. But not often.
