Does having AAA RV Plus work on class A's

I had AAA with 100 mile and RV. My class C broke down about 45 miles from home and it cost me several hundred dollars. AAA would only pay a portion of the cost.
The same thing with tire repair. They allow a certain amount of time and anything over that you have to pay for, Good luck finding this out until you have an emergency. I went to Coach Net. So far I haven't had to use them so I can't say how they are.
