Weird question re: emergency procedures while driving

My parents (both in their 70's) put in 1000's of miles a year with their Airstream. My mom has learned the entire process of hooking up and drives the rig often. She's never backed into a site, however that's not likely to be an emergency situation.

I think it's a good idea, more so if you are inclined to camp in the boonies. We also carry a sarsat PLB so if something catastrophic happens, we have a means to get emergency help.
