I'm not sure if it counts as a survival item but I added extended range towing for the RV to my AAA roadside assistance coverage. They won't tow me home but at least back to civilization to an RV service center. Sorry to say I had to use it last month. The starter and the ring gear failed in-front of my own driveway. They sent a flat bed and after it was loaded it was only 4" under the height limit. I followed them and watched it go under a freeway and it was close, like 1' clearance. Much money later everything is back to normal and all running good.
