I got a Cornerstone ESP from Tom Johnson's when we got the coach. $3,400 for 4 years, $200 deductible, covers the house not the chassis. Chassis coverage was available for much higher cost so decided to just set aside $$$ and not buy more warranty.
So far, Cornerstone has been great. It has paid for several items without any question (new clothes dryer, new inverter, repair leaking coolant fitting on Aqua Hot system, and a couple of other items the folks at CC fixed. According to the service shops I have used (one local, Tom Johnson's, and CC), they were easy to work with. At this point, the fixes have exceeded the $3,400 I paid and I have another two years left on contract. Perhaps now that they have paid out what I paid, they will get more difficult. Hope not to find out.
