Yep- take advantage of the engine's weight as ballast. Some wreckers have rear outriggers, and I've seen operators use the rear spade ( for winching ) as an ad hoc outrigger to keep the rear end stable.
Living in south and southeast TX, we mainly had jobs pulling stuck vehicles out of mud (“gumbo”).
Kids would run around thinking they had a “four-wheeler” and they’d run though a rice paddy or something and I’ve literally seen F-150’s stuck up to the mirrors. They literally had to roll down the windows and climb out because they couldn’t get the doors open, they were stuck so deep.
Somebody would know someone with a D3 and call them out. Often they’d fart around until they got stuck too. Then I’ve seen it where they called out the “real” heavy-equipment co. and they’d send out a D5/6 and they’d get stuck too. Not “bad-stuck,” but still stuck so they’d need help.
Finally they’d send out a D10 with about 6 miles of chain. They’d go back down the line in descending order, extracting everyone.
By the time they pulled the truck out it’d have serious suspension/frame damage. That’s where my little tow-truck (tilt-bed) came into play (that’s what I drove about 90% of the time). You get to see some interesting (and sometimes gross things driving a wrecker). Ha.
