Welcome to the forum...

When I had an old trailer with ramp, considered installing an electric winch to lift the ramp, draw bridge style.  Couldn't figure a place to put the winch though.  With a van body, I would mount the winch under the corner of the box, and pulleys to the top of the box and then a hook to the side of ramp.  One could detach the cable when the ramp is down to avoid snagging a horse leg.  It would be easy to power it from the van battery.
