On a large truck like a Super Duty, it's not.
Problem is, if you want to take such a large heavy truck off road, you will be very limited on the terrain you can tackle without a lift. Your breakover angle is bad on such a long vehicle. I realize that a Super duty is not a Jeep, but I have the best of both worlds as I can go on most trails as long as I can fit between the trees, and I still have a large cargo capacity.
As an off road enthusiast, I love to see a vehicle that is built to be capable on thee trail. Seeing a vehicle that is build up as a "Mall Crawler" is hilarious, and sad at the same time.
Yes, I know, to each his own... well for me, that means slamming anyone who takes a nice truck and ruins it.
