From what I've seen on the forum, most (not all) of these frame problems are on older coaches (pre-2011). It's not about how old the coach is - it's about the design at that time.
I think Lippert beefed things up some years ago - I'd guess maybe back in 2010. And Heartland has stood behind these older coaches even though they're often long out of warranty.
If you want to discuss structural design choices going back to 2008 or 2009, or why someone's coach has had repeat failures, I think you'd need to find a frame engineer. And to get a really good answer, it'll probably have to be a Lippert frame engineer. Responsible decision makers at Heartland don't necessarily have the skills and knowledge for the discussion you may want.
Dan:
Lippert's standard response to frame issues over the years has been: "We build the frames to Heartland drawings and specifications".
