i saw a video where they did this sort of
the rope was not taught though they waited until tree was loose
i thought that the bumper was going to come off or some other mishap

Yeah, that occurred to me when I did it. So I tied the
rope to the trailer hitch. I figured if the hitch is good
to pull an umpteen thousand pound trailer, it's good to
keep a rope (with a few hundred pound breaking point)
taut for a while.

Speaking of which, today's safety reminder - if you have
a taut rope, keep any spectators well back from the
scene. If it breaks, it's going to act like a whip and
mow down anyone within range.
