It's interesting that this thread is at least talking about the two top ERS plans for RV'ers.
Now .... for a lot worse RV Emergency Road Service .... AAA. I dropped them like a hot potato after having been with them for two or three decades. I had a flat inner dual tire on our small motorhome IN OUR BACK YARD last year and AAA told me over the phone that they would not provide ERS on dual tires!!!!! Dah ... last time I checked that's what many, many motorhomes have on them.
I now have Coach-Net Premier, which covers all our vehicles in addition to the RV itself - along with the RV's dual rear tires. What I like best about Coach-Net is uniform service and benefits throughout the U.S. and Canada.
By the way and for what it's worth for our first test of CN, a few months ago Coach-Net provided fantastic emergency service for our family sedan.
