Sounds very limited, outside of FL, GA and TN you are on your own to find a service truck but they will reimburse some day. Also the rates for RV service are based on the size of the RV. Coachnet and/or GS are better deals without all the fine print.
In some ways this is all a little ridiculous. Most likely the same tow truck will come to you regardless of whether it is AAA, GS, or CN. Especially in Nevada and other states where the breakdown area may be very rural. There just are not that many tow trucking companies to choose from. And how hard is it to tow a travel trailer behind the flatbed tow truck with the tow vehicle on board? A fifth wheel might be a little more of a challenge, but a travel trailer?
