My old brain finally remembered an old adage I couldn’t come up with when I posted my first comment:
“It is called four wheel drive, not four wheel stop”.
Chains help with the four wheel stop.
My dad worked for the power company, and as part of his job he regularly patrolled the crude roads under high voltage power lines where they crisscross the Cascade mountain range in Oregon. He thus had vast 4x4 experience. And he was a big fan of chains, for mud as well as snow. Losing traction on a downhill stretch was his worst nightmare. A desperation tactic he employed on such occasions was to throw the transmission in reverse, put the throttle to the floor and try to end up in the uphill side ditch.
He noted that this tactic was best used when driving a company vehicle where you didn’t have to pay the repair bills!
