I urge you to read the brochure. I have had excellent service from Good Sam but I know what I am entitled to.
To answer your question the brochure states;
"When you call for service, the program pays 100% of the towing fees for
the delivery of your vehicle to the nearest independent professional service
center capable and willing to repair your vehicle. However, you must request
disablement assistance through our telephone dispatch center within 24 hours
of the disablement. If you make any request for your vehicle to be taken to
a location other than the nearest professional service center including your
home, the mileage fee (for the extra distance only) will be at your expense"
BTW Good Sam is offering a free upgrade to platinum for NEW members.
