There's no doubt that the curved shape is stronger than a flat shape. But that doesn't mean it's strong enough to avoid flex. And I don't know the long-term properties of fiberglass -- will it sag or relax under stress years down the line?
But people do report problems with their door seals, some times immediately or some times within a couple of years of new. There is *something* wrong here. Reace's current solution is to include several feet of open cell gasket material with a new trailer. This says to me that he admits there is a problem. But I don't believe his solution is sufficient (certainly not for the non-DIYers).
Now I don't pretend to understand what the problem is (though that won't stop me from speculating
!, hence my comments on flex ). I'm just of the opinion that Reace has a responsibility to get to the root of the problem and solve it. Maybe "responsibility" is too strong of a word, but I believe the high price we pay for these trailers justifies our expecting problems like these to be resolved. Or maybe it's better to say that I'm a customer already, but if he wants me to be a repeat customer then it would serve him to keep a cycle of continuous improvement (not just new products, but new *and better* products).
Let me temper this by saying that I think Reace has a very good product, and he does work to improve it. (That is, he's meeting my expectations -- I'm sure he'll sleep better tonight knowing that
). This discussion is just about one of those areas he could focus his attention. It's not the first or the most important, and it won't be the last.
