I'm very happy with my 12 year old $10k trailer. It came from the factory with a couple potential roof leaks, which I sealed with Eternabond right away. It' survived some pretty good off-roading, 2 kids, and a very active Siberian Husky. My wife and I still love it. It's been a great man cave too. I continue to get my money's worth out of it.
In my mind many of the complaints here ARE the purchaser's fault. If the construction was so obviously shoddy, why did you purchase it in the first place?
