I had AAA when I first got my rig, but switched to Coach-Net a year later. I had a mystery electrical problem in the very beginning with my Class A. Called AAA twice, first time I was in my own area and knew who towed and where to go. AAA did the job. Second time I was out of my home area. AAA was next to worthless, they didn't know where I should go and the tow companies they called, then called me saying they didn't have a rig big enough to tow me. I limped the rig back home and fixed the problem myself.
AAA is setup for the car group, not RV's. I did call Coach-Net once, they weren't that stellar either. YMMV
