Its quite a feeling pulling things out like that. In the end, weight is your friend. I drive a "step van" for work. Its a 25 foot truck with a Mercedes diesel engine. It weighs about 10k lbs empty and about 20k lbs loaded up. One day I was returning to work and was flagged down by a coworker. Turns out our fork lift was stuck in the mud. They tried a couple full size 4x4 trucks with no avail. I backed up to the forklift, we hooked a chain up, and I pulled it out like nothing. Barely even felt it. This truck is also a TANK in the snow. I'll say it again, weight is your friend. This is similar to my truck. Its not even big on the truck scale, but it still kicks ass in snow, mud, or anything else I fuck around in while working. The only time I got stuck is when I went into a ditch in a snow storm to avoid killing some lady who came into my lane.
EDIT, mine is dually unlike this pic.
