Ditto what JJ said. There was a syndicate that owned a PW5 at my field years ago. Their trailer was a square section with a huge cradle that rolled out the back with the glider. It probably weighed 3,000 pounds... for a PW5. Made handling a nightmare.

We have a number of 1st/2nd generation glass ships on the field with older tube trailers (ASW-19, Libelle, etc.). Spending some time on optimizing the fuselage dolly as it rolls out the back gate and especially the wing root dollies (stability in particular) is probably a way easier path to better rigging. JMHO.
