Extended warranties are a hot topic. My opinion is there are more losers than winners otherwise no one would sell them. Our Roo is 3 years old and we have had no issues where we would have used it. Most of the major components are covered by the individual manufacturers for multiple years. Forest River was offering a 2nd year warranty for a few hundred $$$ but I believe you had to purchase it at delivery. A lot of dealers don't bother to mention it. If you are handy you can probably handle most small issues yourself. JMO.
