Your Winnebago should of come with a 1 yr warranty on the rv itself. Te motor and power train a little longer. I could say you don't need it and tomorrow you may have to she'll out a couple thousands dollars to fix something. And then a year from now, the same thing. If you have the $7k sitting to the side and available to you,I wouldn't get one. I would invest it into a cd or some interest bearing account and let it grow until you need it. It's all a gamble. It's one of things that if you get it, you probably won't use it. But if you didn't get it, then you will need it.
Do you believe in Murphy? lol
