I feel like chiming in because, well, we're all family here. I often go offroad with my girl... solo. Is that smart, nope. Am I sometimes nervous, yep. But even when we were offroad in Death Valley, Joshua Tree, BigBear, or just local on some national forest fire roads, there were
always some people I could flag down if SHTF with my TJ. I really,
really try to be prepared: food, water, fuel (sometimes, like in DeathValley), tools, spare parts, tire kit and compressor,
HiLift 
, battery jump pack, a pew pew,
and electronics (Midland MXT275 stand-alone GMRS, Baofeng HAM handheld (GMRS accessible), Gaia GPS app on my iPhone, and an ACR Personal Locator Beacon).
So to answer your question, Wildman, in my case my "main, upfront" unit is the Midland MXT275 stand-alone GMRS that remains powered-up and scanning. All others are locked away for emergency. And as you've read, it's kind of a toss-up between CB and GMRS but I decided on GMRS as I feel there are plenty of folks with both mounted and handheld units that I'd more likely be able to ping in the event of emergency (and I can access local repeaters too). Oh no, I think I'm dizzy again... 😵💫
