I recently encountered a similar but much scarier situation, solo. Scary because the slope off the dirt edge was steep enough to be barely hikeable and was at least 3 stories deep.

So, A. would chains make this fairly easy by helping the tires dig in and stay on track up in the snow so as to not slide off into the abys?
B. do lockers help at all with one sides tires being on dirt/gravel and the other in snow?
C. in my experience the front stayed on track as needed (I only had about 24" of road before car would slide off the hill rolling) by simply cutting a small trough where i wanted the wheel to track but rear wheels slid away toward abyss....

D. what i tried was borderline stupid, being solo and at night, trying to get to somewhere i should have just gave up on.

E. halfway through, i was committed due to laws of physics and how the rear wheels kept sliding toward the downhill regardless of my shoeveled cutt tracks ahead of front wheels. (i have no rear locker)

F. some of the terrain response settings work better than others.

G. this was also slightly uphill on the way in. the return went just fine and i was able to lean out the window, over the abyss edge, to make sure i made the most of the gravel half while not being too close.

---- chains best solution? cutting track for wheel to "hook" into really helped though.

Side slope with the rear locker on is in most cases a no-no. It's only going to increase the sliding sideways of the rear end. Open diff is the best on side slopes with limited traction. Mud, slick rocks, snow, etc.

Chains work great in snow and/or mud, but they of course limit speed.

If you back end is sliding out and tracking below you, you want to turn uphill slightly. If you feel like you are about to roll, turn in the direction you are going to roll. Slightly accellerate as well.

that makes sense about the open diff/sliding - you want the wheels 'with' traction to do the primary drive - because more power goes to the wheel with the traction, not the one on snow, so it should hold better - more or less?

i'll go back and get a photo so you can see just how stupid i was for doing it alone ;) had it not been dark, i'd have taken a shot one of the times i got out to clear the snow track again. i had to cut a trench in the snow so the rear wheel would stay up in there.

thanks for the direction. i was hoping to go to one of Bill Burke's sessions out here in NC/VA this month but had to fly back instead of driving it back. I think he's having one in VA and one in NC, maybe more and then not again for a long time they said.

Realizing this is in the LR3 section, but some good educational value here, so generally speaking, what if you have a Detroit in the rear? How do you deal with that?

Realizing that this is the LR3 forum, don't put a lot of stock into my answer, but one of the common "Cons" I read about when people discuss the Pros and Cons of TruTracks verses ARB's is exactly this issue. Not sure if there is a solution.
