Reason I'm asking is to try and determine if a Harbor Freight shop
crane (2 ton) has enough height / reach to slide under the end of a
trailer and lift it up off of the trailer.

Absolutely NOT. Not by far. I own both a bridgy and the crane. The
crane is indispensable, but cannot even approach a Bridgy.

I used a generic 2-ton import engine hoist to lift a Bridgeport off of
a flatbed trailer. It worked fine with the legs all the way extended
and every bolt tightened. Just don't try to roll the hoist around with
the mill in the air - the caster pins will just crumple. I made a dolly
with a lot of clearance underneath to roll over the engine hoist legs.

Pick up mill. Move trailer out from underneath it. Roll dolly under mill.
Let down on dolly. Roll mill to where you need it. Reposition engine hoist.
Lift mill slightly. Remove dolly. Set mill down gently between hoist legs
(make sure ahead of time it will fit!). Remove engine hoist & dolly,
skid mill slightly to get it into final position.
