Ever had TT frame failure?

Thanks for the info fellas. To clear up a few things, yes the frame is steel, the walls and roof structure are aluminum. I'll definitely take it in to the frame shop for inspection after seeing what happened to your Springdale "DutchmenSport". Did you keep the trailer after the a-frame collapsed?

What about the aluminum wall and ceiling frame? Do those ever fail? I'm thinking if I keep this one, I'll remove the air conditioner from the roof since I never use it. That can't help matters with that 100lb hulk just sitting up there.
