Good Sam Tire and Wheel Protection

I have been considering some additional roadside coverage for tire and wheel damage. I drive a class A with a tow dolly. One of the programs I have been considering is GS tire and wheel protection which would cover repair and /or replacement of a tire or wheel on the Motorhome, tow dolly and tow vehicle while in tow. I am interested in what others do in this regard or if anyone has specific experience with the Good Sam program. I think like most, I do not carry any spare for the class A. Thanks in advance for your feedback.
