I give you my experience with AAA.
1) IT IS NOT coast to coast and the help you receive is dependent upon the club area you are in.
2) I had a year with AAA where I needed 2 tows. They were both expensive for AAA as the nearest place for service was 75 miles away on one occasion and about 30 the next time. AAA refused to renew my coverage for the RV.
Now my experience with Good Sam.
4 service calls last 12 months no problems and they renewed my coverage.
Campground Discounts seem to be more available with Good Sam versus AAA
and you get other discounts including free dumping at Camping World as well as discount on fuel at Flying J ( not good for me)
