[Desert Dan]

I doubt On Star will come out and fix or extract your vehicle in the middle of nowhere way off the highway on a 4x4 trail. I am often in places with no cell phone or OnStar signal/service.

I often wheel alone but take fewer risks and I am easier on the vehicle when alone etc.

Know your rig and it's abilities and think about what-ifs like if I was stuck or broken down could I walk the 30+ miles (or more) to get help. If you broke a tie rod or had 2 flats think about what would or could do. What if you had a dead battery?

Think about a rattle snake bite or broken leg while alone. What if the highlift jack kicks out and breaks your thigh bone with a compound fracture?

What if you got pinned under your truck while getting it unstuck? Chew or cut off your arm to get help?

If you are in the desert in the summer or snow in the winter, a stupid mistake or mechanical failure could mean life or death if you are stranded.

Bring plenty of supplies, tools and let somebody know your trip plans (loop, trail route etc.) and time of arrival back at home. Say something like "if I am not back by such and such date and time something is wrong and call for help".
