While I understand that the companies normally come out ahead, I prefer the peace of mind. I am NOT mechanically inclined, at all!
Last Spring over several months, I had an alternator go out, a brake system fail(the dreaded Workhorse autopark) and needed a new differential. This was all on what had been a basically trouble free 2007 Winnie. All repairs were covered. I came out way ahead over what I paid.
In the past I have come out a little under what I paid and about even so I guess my payout odds are better than most, or my repair needs worse. I DO maintain everything on schedule.
For me, I understand it is a bet, kind of like life insurance.......... I hope to never use it but am glad it is there. For me peace of mind regarding large repairs bills works for me. Best of luck in deciding what is right for you!
And yes, I KNOW I could put the $$ in a savings account for repairs. Last spring's bills would have been over $8k. I was inconvenienced but did not go broke.
