If your engine runs it runs. Upside down, dead under water is not so good.

The with truck running is a KEY part. I have had to do pulls where the vehicle wasn't running. Though I admit the more modern fuel injected vehicles are much less likely to be in that position but it is still something to consider.
Also I believe the hydraulics have a tendency to let cable out before the brake catches once the pull is stopped. Which is why the Jeep Club that used to hold Panamint Valley Days wouldn't let a vehicle running a hydro winch participate on the Surprise Canyon run.
