I once took a road through some stuff that was miserable. Mud, sticks, pin stripping, you name it. My problem was that I had a 4 wheeler sitting in the back of the truck. I asked myself why in the *$(( am I doing driving a $30K truck through this stuff when I have a 4 wheeler sitting in the back of it?
It is well worth hauling it up. You can get around quicker, see more, and avoid wear and tear on your truck.
Now if you didn't already own a 4 wheeler I'd say just take the truck.
