You need to shop around, as different plans have different services covered, and different limits, restrictions and exclusions. I find Good Sams ESP a good fit to my RV (motorhome) needs, more so than the road service plan included as a perk with my casualty insurance, or what I can get with the auto club in Oklahoma, although that's what I've been using for years with my other vehicles.
I haven't tested Good Sams ESP, haven't had a need on the road, and when the battery runs down while in storage, I consider that something to deal with myself, rather than something for emergency road service.
