Had the same problems with the shower, but had a good dealer who knew what they were doing. It has to be sealed properly and they were able to get it right the first time. Ours was leaking right under the access door below the bedroom. I think the DVD units they put in these are awful and you may be better off purchasing a different one on your own. See if the dealer will get you a credit, but doubt it would be worth much. I agree with contacting Heartland directly if you suspect your dealer as they will work with you on getting the problems resolved.
