A friend bo't a new trailer from Alabama and within a year the top of the fenders were showing rust. No primer?? It sounds like the Eclipse warranty is good as long as the trailer is sitting on the dealer's lot.
I was considering Eclipse while back (because it's alum and price was right) but after digging out the reviews I decided not to go with it. Price is very attractive but you get what you pay for. I got Adam's instead.
