we can discus this till the cows come home and still solve nothing. Everyone will have their reasons for or against and we have not even gotten into track machines. The simple truth is most simple do not need 4 wheel drive and many that buy them never learn how to operate them just as with 2 wheel drive. The traction will be were the load is unless it in a front end loader. Even then 4 wheel drive will not save you.
Just to make a point the neighbor got his four wheel drive pickup stuck last winter. One wheel on each end would spin and he just sat there. My two wheel drive dually had no problems driving around him with highway tread verses his knobby. I guess my four wheel drive worked and his did not. So for those that think four wheel drive is a save all forget it.
