Apparently, the rest of you never leave the pavement.
I use a tractor for the offroad stuff. Our lil John Deere/Yanmar 955 is narrower than a pickup truck. The front end loader and box blade on the rear will get me out of just about anything, and it will pull trees off of steep slopes easily. We cut trees, then tow two to three back to a clearing behind the house, where we cut them up, split them, and take them to the deck.
I'd go with the front mount. Get a few tow straps, and you are set. Be careful, of course. Might want to seek advice from someone who has logging or rigging experience- my father was a rigger and heavy equipment operator back when he was working construction.
