All three of the campers we have owned came with a spare that was mounted on the rear bumper. Didn't need to use one on the pop-up or Hybrid TT, but did need the spare once on the motorhome.
We were at the same RV dealer that we bought our motorhome from recently and noticed that none of the current year Jayco Greyhawk motorhomes had a rear mounted spare tire. At our seasonal camp site, one of our neighbors bought a Greyhawk in 2014 and his did not have a spare tire. I would hope a spare tire would at least be offered as an option. I wouldn't buy a motor vehicle without a spare tire.
We have AAA Plus with RV. We used them back in March to put our spare tire on when we had a blowout on I-95. It took them a long time to find someone to come out and change the tire, but once they got there, it was done in 15 minutes. The mobile repair guy charged AAA $250 to do the work. That's more than we pay for our service.
We've never had trouble with AAA on the East Coast, where we have used it in a half dozen states, but I have heard that AAA is not as good in other areas of the country. We had Coach-net and wasn't happy with their towing option (have to go to nearest repair center, not where we wanted to go).
