I recently dropped AAA after being with them for decades ... due to their policy (in my area) of not changing the inner duals of my motorhome.
Why would one with an RV remain a customer of an ERS with various policies across various regions? IMHO, this makes no sense for an RV'er who plans on sometimes traveling to/through various regions or states.
I now have an ERS with the same policies throughout the entire U.S. and, I think, throughout Canada ... that's the way an ERS should be.
I also think it's ridiculous to pay out of my own pocket for an RV tire repair and then have to file a claim with AAA later to get my money back. Life's too short for that kind of stuff.
