Okay, I used my ratcheting tie-downs from the gussets behind the steering head to the rings in the floor. I used the non-ratcheting (they call them "locking" ...right) tie-downs on the handle bars to the wood strips on the wall up front, just to keep the front end straight and keep it from "walking." I used rope to spread the load at the wood strips between two holes, a foot apart.
Lastly, I used rope on the sides at the rear to tie from the wood strips (again distibuting the load across multiple holes) to the sissybar. I picked up these funky clips (the real name escapes me) that allow you to adjust the tension on the rope and tie it off without using knots. When I shake the bike, the whole trailer shakes.
Hopefully that will be sufficient.
The other drama came when trying to load it. I made a makeshift ramp out of three 2x4s: two side-by-side with a slightly shorter one underneath tying them together and reinforcing them. I also beveled the ends to better match the angle of the trailer and ground. It is plenty strong enough. I enlisted a friend to help push it up the ramp. The first time the rear tire didn't line up and when we tried to back it off the ramp it backed out of the way and BAM, the front wheel dropped off the ramp. It was less than a foot drop but it freaked me out. I'm going to back the trailer up to a small hill or a curb or something to unload it, hopefully without that ramp.
Oh, and Newt? The kickstand is up and I have about an inch between my taillight and the door. Whew...
