I really don't understand these diesel and grass problem comments. I recently sold 24 acres of sloping pasture I owned. Drove my two different F350 diesels all over it wet and dry and never used 4x4 unless it was sloppy muddy. Wet grass never a problem. I hunt in the TX hill country and we have a dirt and grass "road" about a half mile thru pastures to our cabin. Again I have never used 4x4 unless sloppy muddy. And have never had to use 4x4 to pull the 34' 5er out of a grass RV site.
I don't think I am that much better driver than any one else. :h
