I bought a 2011 sundance 3100es about 1 1/2 yr ago, I have been RVing most of my life. {I am 73} Last RV i had was a Mobile Scout had it for 13 yr very little problems, had several before that Nomad,etc I have already had the Sundance to the shop more often then and one i ever owned. From what I read on here the problems I an having everyone else is having or had. My question is do all Heartland have design flaws??? as this is my first. List so far==landing gear wouldn't come up twice, had to have it welded. Can't fill fresh water tank unless I first blow air outlet. Kitchen slide it peeling off veneer on under side whenever we put the slide out or in. don't have the time or space to list everything. Is this common with Heartland-sundance??????????????? or did I get a lemon????
