Over the years there is story after story about them denying coverage or going out of business. There have been a few people with positive experience on the forum. But all I seem to hear is denied coverage or people having to fight to get it covered.
Like others I would put the money in the bank and make sure I had any issues fixed before the factory warranty expires.
I bought the optional 2nd year warranty from Forest River for $100 dollars and never needed it on my Cherokee.
