2gypsies,
Well, there is no real definitive answer for you. It can take literally a 1/2 hour, if you're real close to a service center affiliated with the your ERS and, has access to multiple size RV tires since there's a zillion sizes and types, all the way to as much as a day or two or more. If you're really remote and your break down happens, again, lots of variables here. We blew a tire, a 19.5" on a Fleetwood Bounder only 20 miles just south of Bakersfield CA on I-5 south bound.
The call to Good Sam revealed a minimum of a 3 hour wait. That was only 20 miles outside of large CA town. So, again, there's no cut'n'dried answer. I can't even tell you what a national average wait would be.
