My truck has literally been frozen to the ground while parked by my camper. Jump in, fire it up, put it in reverse, no-go. WT?, put everything in neutral then pop 4H and try again, still no joy. Go to 4L creeper and ended up with frozen mud shoes on my tires. I had to chip that stuff off before I hit the road, but didn't get it all, and it let me know that.
Potentially could get close to that cold tomorrow, but I'm on pavement this time
