And congrats on the new TT. There are many happy Windjammer owners here on the forum.
As for the warranty questions, make sure to spend the $150 (maybe it is $200) to get the second year factory warranty from Forest River. I decided that the other extended warranties, which tend to cost thousands of dollars, were not likely to be worth the money in our case, but that is purely a matter of personal preference and finances.
