I bought my truck as a 4x4 not sure if I would be glad i did or not. I am still not sure.
The front end simplicity of the 4x2 is a lot more reliable. And it steers better.
It always bothered me that to get a part time advantage, I have to pay a full-time price with the 4x4. So what is the advantage worth to you?
While i live in GA, the 4x4 was a waste of money. Here in Cheyenne, I have never regretted getting it.
The 4x4 doesn't steer that bad, and seems a lot more driver-friendly than I would have thought. I don't have the CAD on my truck, but still get decent mileage.
4x4 is almost NEVER a true need-- it's a luxury in most cases. If you switch to a winter tire and put weight in the bed, you can use a 4x2 almost anywhere year round.
But i sure like the luxury of not having to buy chains, add as much weight, or call a tow truck. The huge weight of the Cummins give the front end a LOT of drive traction, so 4x4 has been all i need even with those crappy Micheline tires.
The wife REALLY likes 4x4, and we take out the truck over the fwd car when the snow is bad.
