What you will see in this slippery ramp situation (and truck in "park" and 2wd, but still sliding down the ramp) is one rear wheel turning forward and the other turning backwards. Having a limited slip won't overcome this. The parking/emergency brake will lock both rear wheels.
I would make #1 If you don't have a 4x4, buy one and use the 4x4!
I have always owned a 4x4 for this reason. When I make my last turn to the lake I engage it. Now the 4x4 system on my 4runner is by far the best system I have every owned as far as being user friendly but have never buried it in the mud like I have my Dodges that system works well too but tend to bind on tight dry hard surfaces when they turn hard. The Runner you never know it's engaged other than it goes. No additional noise or loss of fuel mileage that I could ever tell and this is our second runner.
