Often with a extended warranty, IF towing is included, you have to pay the tower and then submit a claim.
With Coach-Net and most other roadside assistance programs.. You call, they send, you do not need to pay anything.
The worst I ever had to do was educate the tow driver... I'm a bit better trained than most of 'em in the area of physics.. Thus when it comes to figuring out how to do heavy lifting or towing.. I have the advantage.
Home is where I park it!
