I agree with Mark. There is so much that can go wrong with an RV that it is one of the few purchases that I believe an extended warranty is worth the cost. Let the air conditioning unit go out and you've paid for the warranty right there.
As for your list of issues, I agree that CR should cover the remaining outstanding items, although you had best get them documented with CR and the dealer if you haven't already. I had a Forest River product that I had a litany of mostly minor issues with a couple of more concerning issues the first year of ownership. For that one, at least, I can say that all my issues were corrected the first year and I never had another problem until I sold it. It sounds like most of your problems are minor and you will probably be a happy camper this year. Good luck!
