I've seen some posts here and there talking about frame flex as evidenced in seeing a crack in the fiberglass below the front slide. I haven't seen anything to indicate a systemic issue with any one brand or model. It seems to me to be a "one-off" issue like many other manufacturing defects. Since it's all built and assembled by humans it's possible for anyone to end up with a problem here and there. It's also difficult to determine how any particular rig was treated or what it was exposed to in travel that may have encouraged frame flex. My own layman observation is that it's typically the longer trailers (38-42') that might be more susceptible to flex. I have no scientific data, just personal observation.

I wouldn't hesitate to buy any of the models you suggested. The HC's use a 10" I-beam frame. I'm not sure what size the Avalanches have.
