D-6 Cat.....handy and somewhat portable!
Saw a guy pull a tree onto his truck about 10 years back, using a winch. Tree was all rotten inside and just kinda broke off and landed on the Blazer.

The only time I ever needed a "deadman" and nature wasn't helping, I was lucky enough to have a few T posts in the truck. Sunk them at an angle away from the pull, and hooked right at ground level. It worked, but barely.
