Well, I don't think any of us know if you are stupid or not and I doubt we care. And being stupid and being ignorant about some subject are two different things as well. The point is, you seem to be assuming that the reason others have not suffered the problems you have is because we've just ignored them. That's insulting and just wrong. Some trailers are built better than others. Sometimes folks choose those, sometimes we just get lucky. Sometimes people get stuck with a lemon. I'm sure you thought you were making a good choice when you bought your trailer, sorry it went wrong for you. At least you were able to fix some of the defects.
