I once had a flat on one of the rear duals that I discovered on my Class C while it was sitting in my back yard just before heading out on a trip.
I called our traveling friends to wait up for us and then called my AAA ERS.  They said that "they didn't service flats on dual tire sets" !!!!! (huuuuhhhhh?)
I canceled AAA (after being with them for decades) and never looked back.  I now have an ERS that is all about RV road service -> Coach-Net.  (They're comprehensive - so they also function as an ERS provider for our pickup and sedan.)
