Hello from a rainy day in Munich. GAW, no flying at Unterwossen for me either!
Frank's simple system works well. Perhaps use a tarpaulin on the ground for
places where the carpet would pick up stones or burrs. Build a cuff with a pin
on it for the wall of a clam shell trailer if the spar sits below the top of
the wall. Believe Cobra sells them as an option.
Tom and Billy Stowers' Minden Fab tube trailers from the 70s had a similar
system to your description of Bruce's. Wing root dollies extend beyond the
trailer and pivot in two axes. Frames with dollies on top serve as wing stands.
Several SZD42 Open Jantar owners have these trailers and can solo rig.
Using any of the commercially made solo rigging systems (Cobra, Wing Rigger,
Tool Tech, Udo, etc) it is not necessary to have the spar pivot in the trailer.
But these cost over $1000 more than TA's roller. If there isn't 20 knots of
wind it's quite easy to assemble or put away a modern glider alone.
At least you can derig by yourself under GFA rules, without an additional
rating.

The carpet covered tube is brilliant. It is easy to make something complicated.
The hardest solutions to arrive at are the simple and easy ones.
That's why you want smart, lazy people.
There are actually two inventions here though. The second isn't very visible.
He's modified the wing root dollies to have flat tops with removable pins so
that he can rotate outwards and then pull the pin and twist the wing flat.
An even better mod is to extend the wing dollytracks with a removable extra
section to take the wing root outside the trailer body. Bruce Tuncks invented
that idea. Means you don't have to reach inside the trailer. I've been using
that since 1984.
Anyway, after all that, the invention is pointless in Australia as the bozos
running the GFA insist on a second person to inspect and sign the DI. Funny how
there is a world market for one man rigging devices to make you independent
isn't it? And how the selling point used by manufacturers of motorgliders is
"independence". Still wondering why gliding is going down the drain?
