Holy reviving a dead thread batman...
Anyhow, I just needed to put in my $.02 about Pedal Braking VS. Engine breaking, and the choice of the 4x2 over the 4x4,
They do the same thing, and engine braking by no means is the solution for slipping on ice. Sure, if you are stomping on the brake pedal like you are trying to put out a fire, then by comparison, engine braking will cause you to slip less. The only reason for that is because it is a more gradual process. You will get the same effect if you slowly depress the brake pedal. I'd even argue that because the brakes apply stopping force to all four tires, and in a 4x4 only two of the tires are working during engine braking, that you would stop better with a gradual application of the brake pedal.
Anyhow, I don't think you made a bad choice with the 4x2. You saved $2,000, and you don't have a use for 4 wheel drive. You live in NYC for goodness sake.
Along with my Liberty, I have an old '93 for ranger rear wheel drive, and I have taken both out in large snowstorms, with 2+ feet of snow. (I'm in the snow belt), and I can say that I have never gotten stuck in the Ranger. It's all about driving for the conditions, and knowing when and how to use the brake pedal. I have 4x4 on my jeep, and when I first got it, I thought it would be impervious to slipping. It's not, and I found that out quick. I have to drive just as carefully in my Jeep as I do in my Ranger.
Being in NYC, you won't have a problem. Unless you try to plow through snow drifts at 60 miles an hour while "Engine Braking", that is.
