There is no manufacturer warranty offered by Forest River after two years that I have ever heard of.
It may be possible to buy a"service agreement" from a third-party that is billed as a warranty. But, these are not extensions of the manufacturer's warranty. They are generally expensive and the coverage can be very limited and might require you to jump through hoops. Its buyer-beware.
