Another one wheel trailer
I pull a one wheel trailer with my Ultra Classic. It is an N-Line made in Des Moines Iowa. It's quite a bit longer but has about twice the cargo space and about the same weight. Here's a picture of my rig. I have pulled both two wheel and one wheel. The weight is much less with the one wheel, but you have to hold it and the bike up. Not a huge deal to me, but you have to be aware of it. The advantage of the one wheel is it leans and turns with you. I have gone through twisties two up and the trailer down to floorboard scraping and the trailer was no problem. It does get pushed more by the wind than a bike alone. I do not load mine to the full load capacity. I stay around 60 lbs. I went heavier but didn't like the feel. Hope this helps.
