Check out the trailer web page George posted.
I used to travel with my VW powered Kolb MKIIIC quite a bit. I must have pulled it 8,000 miles and never had any damage to my plane. Get a trailer that is sprung for the weight of a Kolb. A trailer that is designed to carry heavy loads will transfer the road bumps to your plane. Support the tail and wing tips. Also support the wing roots to keep from stressing the universal joints. Use a enclosed trailer and you are good to go.

Kolbs do just fine trailering on main gear.

It is recommended to fabricate a pedestal to carry the tail boom and take the load off the tail wheel and tail wheel strut.

Long distance trailering I removed the wings and secured in cradles on each wall of the trailer.

An enclosed trailer is best for long distances and highway speeds.

Open trailer for local traveling to and from airstrip.

It is hard on the aircraft to tow at highway speeds on an open trailer.

I've towed my Ultrastar, Firestar, and MKIII on the main gear with the tail wheel assembly attached to my tractor.  It is 3 miles from my home to my grass strip.  I did this with wings removed.  Wouldn't want to do that every time I flew.  Always scared to death some idiot was going to run over my airplane on the highway.  Always a nail biter.

Homer Kolb designed folding wings on the Ultrastar and each model thereafter.  It was always a big selling point.

I don't fold unless I have to bring the airplane home to work on it.  Haven't had to do that in many years.  Instead of clevis pins I use AN bolts and nuts to attach wings and flying surfaces.  All fittings have welded bushings.  No slop in attachments.
