About 10 years ago right before our maiden voyage in our first RV I purchased a coachnet subscription. I think it was about $100 if memory serves. My wife was pretty irritated and thought it was a waste of money. Fast forward a few days later and we are on our trip, it was a cold Sunday downtown Pittsburgh and our car broke down. Called Coachnet, they asked if we were in a safe location and they started things rolling. Called back 10 minutes later to check on us and say they could not find anyone in their network but they would start going through the yellow pages to find someone. Another 20 minutes and they called back and said a tow truck was on his way and stayed on the phone with us til they got there and knew we were ok. They towed us back to the CG - about 40 miles - no charge. The tow driver said he liked that Coachnet paid him right away - unlike GS which invoices discounted rate checks monthly. Said he often dodges GS calls because they are a hassle to deal with and get paid. Said he was signing up to be in the CN network.
Anyway, that was our very first outing and CN came through and the service paid for itself in a week. Wife wasn't so mad after that.
