We have AAA RV+. Only used it once, locked myself out of the camper. They responded quickly and opened the door. Main reason we went with AAA is DW travels extensively around the country and rents cars at her destination. AAA covers the rentals too which she used in SoCal after locking herself out.
My brother has a DP, winters in Yuma and summers in Fairbanks. He has Coachnet and can't say enough good things about them. They've towed him in twice that I know of. Once somewhere in Wyoming and another time in the middle of nowhere on the AlKan.
