I carried both GSRA and AAA until a year ago.
When we were in San Diego last summer at a very popular RV park my tow vehicle broke down. It was driveable, but Ford advised us NOT to tow our 30' trailer. They couldn't repair the Expedition before we were to check out of the RV park so we needed to figure out a way to get the trailer out. My first call was to GSRA, asking if they would tow our trailer to a storage area WITHIN the RV park. They said that doing so would constitute a "courtesy tow" and said no dice. Remember, my Expedition couldn't do it's job of towing the trailer and GSRA didn't know that the car was still driveable. So I called AAA. I have the RV rider, which got me a wrecker that actually towed the trailer back home -- about 120 miles -- for $75 (over 100 mi. limit). I cancelled my GSRA the next week.
I think looking at both policies would be a prudent thing to do. Since I'm not traveling full time and out of state much now, I'm sticking with AAA. When I hit the road after I retire I'll probably look at CoachNet.
