So what do you do when truck gets stuck

I'd have threw a tire chain on the ground so he could get moving.
Depending on his attitude,

 

If you ran a large company of new, inexperienced drivers who went through typical entry level fleet 'training', do you think you'd spend more on winch outs without the lockers, or on tires with the lockers, though?

 

All true, but I'm not sure I'd drop a loaded trailer in that parking lot. Might sink.

 

They put people in trucks like him. Scary. As a X logger & Pipeliner chains in mud is no big deal. Heck I've chained in 2 feet of powder dirt. It canbe just as slick as mud.

 

Sheesh, what an Idiot! You shoulda told him, "no, I don't want your change, I want all your folding money..."

 

I suppose that goes without saying..... but it had to be said

Of course, put cribbing down or whatever you need to do to keep it from sinking, if you are loaded.

 

Had that happen on snow at a dirt lot in Mt. a few years back, skateboard parked behind me was kind enough to gently back into my trailer and give me a nudge to get me moving.

 

power divider, first gear, rock the steering wheel.

always worked, if it didn't, ask for a tug, if couldn't get one, I'd have to evaluate, either shovel + some kitty litter and if that wasn't feasible, wrecker would be last resort. these days I usually put put around the yard in a goat, and not drive a tractor into mudholes, so it's not an issue.

 

Oil dry salt any of those should give you enough traction to get out.
