I built a trailer using the running gear from an old Boler travel trailer. It has 14" tires and rubber torsion bar suspension. The hitch draw-bar is 2"square tubing built to extend as necessary depending on A/C type.
The sloping tube (to maintain level travel) has a sliding rack that pins to the two main "carry through tubes" at the lower longerons just ahead of the tail skid. I have a Vixen but the setup is the same on a taildragger. A winch mounted at the top pulls the A/C on easily. The frame is lowered at the rear in order to have the A/C wheels only about 4" off the road for good handling. I can load/unload in minutes. Most of the time is spent fueling/unfueling and pre-flighting.
I have some pics,if anyone is interested I will forward to your email address.
I also built a box on the trailer for fuel, tools,tie-downs,etc. I brought the A/C home from CA and also traveled for every flight before I was lucky enough to find a hanger to share.
