Sorry you are having so many problems out of yours. It is frustrating when you buy something new, and have so much go wrong with it. But, from what I hear, its an ongoing problem with all the companys making RV's & TT's. There does not seem to be much quality control in them. Then others say they have had no problems at all with theirs and are as happy as can be with their purchase.
