Jim,
I think what you just described is what Heartland and the Heartland Owners Club does. If you think that they do not pay attention or make changes to their product lines based on this forum and the feedback they get from their owners you are greatly mistaken. Not every issue that each owner has can be fixed or the product lines altered in a timely manner. After having had 6 RV's from 4 different product lines, I can honestly say that this forum and Heartland RV's has the best customer service I have come across in this industry, bar none! On top of that, this owners forum is the best in the market as well. Sure there are a lot of individuals here that are loyal to the brand, myself included, but that loyalty is well deserved in my opinion!
The reality is that the entire RV Industry and their quality control could definitely use some improvement, but understand that in doing so that creates more cost per unit. Heartland is always improving their lines and I think listening to the customer. They truly want repeat customers and it shows when you talk to them.
Heartland can not control their dealers and the service they provide as they are independent owners and are able to run their own dealerships and repair facilities they way they see fit.
In this case, there are some people that have complained about issues with the ladder, and the 300 pound weight rating is probably overrated, however Heartland RV's does not set that weight rating, that is set by the manufacturer. In addition, Heartland is and has been making changes to try and improve the ladder and make it more stable.
Like other have said in this thread, there are FAR more people that do not have problems with their ladders than do, and Heartland and Atwood have to evaluate that when considering changes to their product lines.
This entire thread has gone way off course and should probably be redirected back to the original questions and the nature of his ladders failure, which was not the issues that are causing most of the complaints about the ladders to begin with.
I contacted Heartland and they said that they do sell the new Landmark mounting plates, which they claim make a big difference in the stability of the ladders.
Good luck all and safe travels!
