I am considering trading in my rig for a new dually and want to know readers opinions on what they would consider the best option; a 4X4 or 4X2. I plan in the future on occasionally hauling a 5er and also an enclosed car trailer. With the 4X4's I have had in the past they were nice to have except I found I just never used the 4 wheel drive part very much. Now if I go with a 4X2 I would have the advantage of better mileage and cheaper first cost - however I lose that flexibility of having the 4 wheel drive if I were to ever need it. So I guess my bottom line question is for those 4X2 folks out there - how many times you wished you would have had the 4X4??
