"Have AAA premium road service. "
While I do not know for certain I have been told that AAA will not come into a campground and will not change an inside dually. If I had AAA I would take to the time find out for sure one way or the other and if you do please get back to us to confirm or squelch this tale.
Regardless of your ERS provider having a spare gives you options and likely will get you quicker service when you have a flat/blowout. The tech that came out to change my blowout was just driving a midsized pickup with an assortment of tools in the back. If I had no spare they would have had to dispatch a truck with the equipment to mount/balance a new tire that hopefully would be available.
Storage and mounting will always be an issue for most folks. My spare lives under the rear of the coach as I had Nexus install a custom mount when I visited the factory 4.5 years ago. Before that I in stalled a spare tire mount on the rear bumper. It only took a few weeks on the road for it to fail and fracture the mount... there was just too much motion and weight involved. My spare is too large to fit into the primary storage bay.
