Our 2015 White Hawk had some shower issues that caused a wall to start sagging and falling apart in the kitchen side of the wall. We contacted the dealer and sent him required pictures. He told us he would order a new wall panel from Jayco and thought he would have it in about two weeks. I figured closer to a month, if then.
About three weeks later, the service manager called to say the panel was in and when could we schedule it's installation. We went up the following Tuesday and told him we could not return until Thursday or Friday at the earliest, so no rush. He called Wednesday to tell us it was ready.
When we arrived Thursday, he had forgotten that they were going to remove and re-caulk the entire shower stall. So, we killed a couple of hours while one of his techs could finish the work.
Sounds like the OP has a legitimate beef with his dealer.
