I doubt your issues will qualify under any sort of lemon law. Usually, it is three repairs for the same problem, and even then, I think it is pretty hard to enforce.
Sounds to me like typical new unit issues. None of them seem that major to me. I can't speak about the floor bubble though. It is normal for there to be some expansion, contraction in sheet vinyl in an environment that seems temperature extremes. I've never seen that issue in my unit, but I have heard of people finding rips in their flooring after a cold winter. I'd try cooling the unit down for a good long time and see if the buble resolves itself. If not, I'd live with it and then bring it in for repair at the end of camping season so you aren't out the use of your TT for a long time.
