OK...to get back to the OPs topic of interest on extended warranties...
I did a fair amount of research on extended warranties. I do agree with the thought that its ideal to save your own money in a rainy day fund and hope that you'll not have to use it. But, statistics will prove 2 things: 1) Something costly will
fail and require replacement/repair on your RV eventually, and 2) Most people are not self-disciplined enough to save the rainy day fund.
With that said, we opted to purchase the XtraRide Extended Warranty. I thought it was reasonably priced and did not have so much "fine print" as many others. One thing to look out for in choosing one is the requirement for maintenance history. Many of these warranty policies will not cover repairs unless "adequate" documentation can be provided proving that the part/system in question has been properly maintained. This puts alot of responsibility on the RV owner to collect receipts, paperwork, and ensure each and every component is serviced to the exact requirements of the OEM. I don't know about you, and I'm all for preventative maintenance and inspections, but camping should be fun, not a chore. If something brakes or fails and its obvious that it was not mistreated or not cared for, honor the policy, fix the darn thing, and lets get on with life...just my 2 cents.
