In addition, to the OP...you could of called a towing company. Either looked up one or asked GSRA for the name and number of a towing company. Also, you should chekc your insurance policy on your motorhome. Many insurance companies include roadside service in with the policy. Also, you can call the local law enforcement agency and they can give you info on towing companies.
And as others mentioned, it's a good idea to carry a spare. Would save on possibly paying for a tow versus having them change the tire for you. And with a tow dolly, it would be something you could probably do yourself with the proper equipment. Just things to think about.
