My wife and I have been AAA RV Plus plus Good Sam Road Service for several years now.  It costs more but there are a couple things you need to know about the differences.

AAA Plus
4 tows/calls per registered person, up to 100 miles.
Will tow if accident involvement.

Good Sam
Will tow you to the first place that can do the proper repair, unlimited mileage.
Will not tow you if you have been in an accident.
I think the number of tows or calls is 4 per person.
Must have a camper van or RV in order to get the coverage.
