There is a local pilot that trailered an Avid down from Alaska.
He did not use the support tubes from the leading edge spar to the lower
wing strut attachment.
He completely destroyed the fuselage center section where the rear strut
attaches.

Bob-
I welded up the trailer in my driveway specifically to fit the Avid --
it is a single axle with minimal spring stiffness --2 leaves. I live on
the outskirts of Wash. DC and have to trailer the bird some 50 miles
each way to Frederick Muni each time I fly to get out of the ADIZ. The
mains are secured with tire chains and the tailwheel is secured with a
specially welded up clamp. I have recently added supports for the
empennage which fasten iinto the cross tubes for towing on its own
wheels which takes all of the weight off of the tail spring. I will
attach a couple of photos, but the trailer details can best be seen
posted on the Avid Flyer list under Pops' Avid A.
Actually, while trailering, the wingtips are right behind the car's
rear window, and their movement can be observed easily. The struts that
hold the wings in the folded position will keep the wings from swinging
out, but do little to restrain their up/down movement. This is why I
added the struts down to the cross tubes to triangulate that support
location. Without the added struts, the tips would move up and down on
rough roads. Presently, the tips are absolutely fixed and no movement is
possible. Other than truck vortices, I have never observed any wind
generated movement since adding the braces.
I haven't used the front spar braces, as I don't think that do much
with my triangulated wing support taking the load. My attach point
failure occurred some 7-8 years ago, and I did a lot of thinking then to
make changes to prevent it from ever occurring again.
