Use what you have to get the job done, Sure beats a tractor jack

Concreted fence post, but close enough. I have brush stumps to pull this weekend, there has been just enough rain to make feasible. Attack will be trailer receiver, 4WD, a jackpole, burlap and 5/16" tow chain.
Pictures will be taken; shared if not a howling failure. There's about a dozen, so probability says with a few tries, at least one will finally become presentable.

Depending on how much force you need to break the load out of the ground, that is a good way to ruin a dump truck. The hydraulics are powerful, but intended to lift a load that is pretty much balanced between the side walls of the dump body. Obviously the trick worked in that video. With any big equipment, just because it is big and powerful, does not mean you cannot break. Powerful machines are powerful enough to hurt themselves when used improperly.

And anyone stood in range of the flying debris/hydraulic fluid jet...

It would have been a lot better for the truck, and had better leverage, to back up to the post, raise the bed, then tie the chain off on the center of the gate, then lower the bed.

It really doesn't take a lot to pull a cemented post out of the ground providing the bottom of the hole was not belled to a larger diameter than the hole itself. Once the initial suction and friction has been overpowered you are only lifting weight. Raising the bed about half the way then using the top of the tailgate allowing the weight of the bed to come back down using only gravity that is one way. Connecting off the side of the bead near the front will obviously allow for more travel, it's not likely there would be much more stress if any, on any part of the truck as raising a load that was loaded higher to one side than the other would do.

Visualizing this one would be my pick. Can see a length of angle iron over top of gate to distribute load on sheet metal, and no real load on the hydraulics at all.
