It's funny you asked that question because 2 days ago my buddy, who drives a FORD...sigh..., was stuck in the snow/mud. Now, keep in mind we live in north Texas, and this (snow) is not a normal thing, especially 8+ in inches in March. But nevertheless, we get out there...I pull my truck about 10' in front of his and jump in his to get it out. Well I realize that I'm gonna need some more space so that I can "gun it" so I tell him to pull my truck up about 20 more feet. The next thing I know I see my truck sliding into the same ditch he's in and I start honking and flashing lights...but it was too late. So now we've got two trucks that are stuck...wrong. I jump in my AV and put in 4-LO and get to work. A couple of mud-ruts later and some wasted 87 Octane and I was free...that 4-Wheel Drive worked BEAUTIFULLY!!! I don't have any cool upgrades or anything else, just factory size tires and factory suspension on an 2002 Z-71 with 130K miles...but that thing drove outta that mud/snow like it was made specifically for that purpose...I must say I, and my friend, were MORE than impressed. I FREAKIN LOVE MY TRUCK!!!!!
P.S. His truck stayed there until the snow cleared!!
