I have a motorhome protection plan. It's my Capital One $12,000 Visa card. Cost me nothing if I don't use it. If I do have to, it's cheaper than an extended warranty.
The only person I have ever talked to that was TRUELY happy with a warranty plan was a friend with a 2006 Newmar Mountain Aire that had a Good Sam plan at $186 a month, a $1000 deductible, and roadside assistance. He claimed to be ahead of the insurance company, but last I talked to him, due to Covid and his coach at the factory for some siding warranty repairs for 5 months, and still paying $186 a month, they got ahead of him by about $3,000. Since Newmar was replacing the siding under warranty, but he had to pay for the paint, he tried to get the warranty company to pay for it. NOPE. And as he put it, he really has had more non covered repairs than covered, as most were under $1,000.
