I modified the oem adapter plate so it will fit through the opening that is hole sawed through the riser on the stairs. I had to do some custom grinding on the remaining components to get it all to fit but it works as designed now. This is the kind of QC stuff where Heartland needs to do a better job. I am also quite appalled at the wiring and plumbing rats nest behind the bulkhead. Good thing I will have some time this month to fix it all. Still a happy Heartland owner though. I would also like to give my dealer, Gillette Rv, in Lansing, Mi. a big thumbs up. David is their service manager and a stand up guy. Highly recommended for both service and price.
