Please don't take these issues as quality problems throughout Heartland brands, a lot can influence the root cause of your problems that can range from a lot of things that happened after leaving the factory until you took delivery. Everything from rough handling during transport to dealership demos, or RV shows. I know in just the 3 days from the time we looked at ours at the dealership till we said "OK, we'll buy it" (Sunday morning until Tuesday afternoon) enough people looked at it to cause damage that wasn't there 3 days earlier, such as some idiot that didn't realize how to open the the cabinet by the cabinet pull and tried to open it from the wrong side and cracked the cabinet door (covered under warranty).
As you can see in my signature, I own a 2015 that still hasn't made it home, but mainly because the PDI my dealership did wasn't up to "my standards". When I did my walk through I threw them for a loop when I showed up in my wife's car and not my truck, and pulled out a creeper and a bunch of tools to check over everything. Granted, I did my research and knew pretty much no Brand or RV maker will deliver something cross country and have it get there in great/new shape, most RV's are built in Indiana and to get it to Oregon for me, or Wyoming for you, it was hooked to the back of the lowest bidder and delivered to your dealer.
For mine, it has a leak in the fresh water system where the entire underbelly was full of water like a water balloon when all we had tested at that point was filling the fresh water tank. I can only assume that the transport operator just doesn't take as good of a care of avoiding bumps, or road issues as an owner would and something just loosened some of the fittings on the fresh water system, but haven't really heard from the dealership as to the root cause of the issue yet so I cannot blame Heartland quality.
Like I said though, I showed up for my PDI fully expecting issues, and since I never took delivery the dealership is setting everything as a higher priority just to get it delivered. Sorry to hear about your issues, but you should take it to your dealership to get resolved, and if your not making headway with the dealership Heartland will direct you to an independent local RV service person that could take on your repairs as others have pointed out.
