I had/used one for 15 years but never saw a manual for one. I have no
idea how many variations of fittings there were but my wing root
fittings were set up to use the single man rig system. That design
had a weakness. The wing root fittings ran on one track on the side
wall and one track on the floor. With age the floor sagged where the
fuselage dolly sat and changed the geometry between the side and floor
rails. This allowed the root fitting front wheels to jump out of the
tracks which is very inconvenient. The problem is compounded because
the solo rig design required the root fitting to extend beyond the
trailer tracks which means the root weight is not all between the
wheels and tends to make the front wheels of the root fitting rise
when the wing is pulled out of the trailer. (the fitting design allows
the wing to be pulled out, swung round nearly 90 deg to the trailer,
then rotated flat, all before the spar is removed from the trailer
fitting)

If your wing root fittings use the same arrangement suggest after you
rig you run each root fitting up and down the track and make sure it
cannot separate. Holding the wing tips as high as possible without
hitting the end of the trailer helps to stop the wheels jumping out.
Careful adjustment of the wheel offsets helps. I ended up resorting
to drilling out the track rivets and shimming the tracks away from the
floor in the sag area The proper fix would probably have been to
eliminate the floor sag.

I never had, or used, the solo rig wing support so can't give you any
advice on that.
