I was offered the extended warranty from my dealership, along with their insurance department services, their financing, a lifetime wax coating, and probably some other offers I don't recall. I turned all down, but quickly sent in the form for the extended year Forest River warranty. When used during the second year, there were no problems at all with FR honoring the warranty and covering all the costs.
