I have the slam doors. Love them. However had problems with one when we picked it up from the dealer on day one. It rubbed on the top of the frame when we opened the door, figured it would be only a minor adjustment and i accepted the rv and figured i would adjust the door later. After using the door a few weeks it kept getting worse. Tried to adjust it and figured out it was the outer part of the door coming unglued from the styrofoam center of the door. Called heartland and reported my problem. Asked if i could try and glue the door back together as my dealer was 2 1/2 hours away. They said they would send me a new door if i thought i could change it out. They sent the door no charge ($485.00) list price on the packing slip. I was expecting only the door which i needed. I received the complete door, frame and new lock, all installed and ready to install. (made by lippert) no problem changing it out,and installing the unit. (had to work to get the old door out as it was glued and screwed to the rv). Have had the new door in a month or so, guess what, it is starting to do the same thing, coming apart. I think this time i will put 2 pop rivets thru the door on the top to fix the problem. anybody else having the same problem?
