I bought an Easy Care 7 year policy right out of the chute with our new 40DP. That was five years ago. We've used them probably six times for issues ranging up to slide repairs, leveling jack repairs, and the replacement of my Winegard automatic satellite dish when it went belly up.
They've never once denied a claim... in fact I've never spoken to anyone at Easy Care because the shops I have used are all willing to work directly with them... because they know Easy Care will pay them promptly. I've also never had to pay for repairs and then go to Easy Care for reimbursement.
So I hope you have the same good luck with them that I have had so far.
There are some things I would do differently if I knew than what I know know:
1) I bought the policy when the coach was brand new instead of waiting for a year because Winnie's warranty covered virtually everything during that time. In fact the chassis warranty is even longer so I'm really paying for "double coverage" in a way.
2) I bought the policy from my dealer instead of dealing directly with Easy Care. Hand in hand with this is the fact that I didn't negotiate the price.
The dealer puts a huge mark up on these and will negotiate big discounts... or even throw it in with the purchase of a new coach. They get you when you're all excited about your new purchase and you think you're negotiating is over with. Then the finance guy hits you with the sales pitch about how expensive these things can be when they break.
Bottom line is that it bought us peace of mind. We weren't looking to "come out ahead" on the deal but wanted to avoid huge, unexpected repair bills.
Best of luck.
