Anyone have Coachnet Tire Hazard Contract?

I was looking to getting a tire protection contract and after careful reading of the 'agreement' I see that covers only punctures and it excludes a puncture from anywhere that isn't a paved public road (so private roads are excluded).

So lets say you drive into a RV park that has gravel roads and park at a gravel site. Next morning you have a flat. In this case, Coachnet could deny coverage...but would they? Same thing with driving to Alaska, I recall kilometer after kilometer of unpaved highway in Canada.

Anyone have experience with CN's Tire protection? Are you happy with the coverage? Have you tried to make a claim?

Are there any suggestions of an 'All Hazard' tire coverage contract available through some other company you might recommend?
