We have AAA plus RV. 3 years ago, we lost a tire on Hwy 290 coming out of Houston during rush hour. We got to the shoulder, but could not change the tire without something blocking traffic- I could not even stand next to the trailer while cars blew by. I was very scared for my family. AAA came through for us big time that day.
I have not needed them since that time, but that memory makes it very easy to send in the payment every year. I also try really hard to avoid high traffic times in cities.
I will keep roadside coverage, but I don't have any experience to say one is better than the other.
