Anybody use " RV Warranty Forever" service?

The Unit I'm looking at is supposed to have this "Warranty" that comes with with it. My Question is, Anybody have any dealings with these people, Of course all the literature with it looks like the promised land, but My Chronic Unease tells me to check on this. There is NO co-payment, and you have to get it inspected 1x a year by a qualified service center. I have no Idea about what warranty is actually good, so I need to me real people advice.'
