I've been "overlanding" for over 50 years. 99% has been alone or with my wife riding shotgun. I grew up in the mountains of Colorado on a ranch in the mountains.
Rules:
Always have someone who knows when you are supposed to be back and check in upon returning.
Try to let someone know where you are going, or at least the general route.
Know your limitations.
Know your vehicles limitations.
Use common sense. Leave your testosterone at home.
Always lay out an alternative route before hand.
Carry lots of spare parts and the tools and knowhow to use them.
Know how to recover a vehicle and have at least the basic equipment; strap, shovel, ratchet cable winch.
Use common sense. Plan your route over an obstacle. Plan your recovery if you get stuck/hung up.
Remember...you may have to come back over the same obstacle.
Consider your self to be on your own. Have survival gear and rations.
95% of the places I go have no cell service. I have a 2m ham in my rig but 90% have no repeater service.
A SPOT or Garmin Satellite communicator has finally gotten more affordable, but when I needed mine most, it didn't work
and I had to walk out 28 miles on bad knees (now both recently replaced)
A SAT phone is a viable option as well. The key is if you are beyond what you can manage to hike out on foot and you don't have all of the above
DON'T GO

You said it all. I’ll add that, for us, our loaded up backpacks including a PLB are our grab bags. Gotta be able to walk away.
