That's a great looking hitch WayneC, love the trailer too.
As Eight433 has already demonstrated, there's a few of us that like to build our own. (nice trailers too btw Eight)
I've been thinking of a mono-wheel too. It must feel a lot safer being that much more narrower. And of course having the frame adjustable would be a huge bonus. I feel fat with a two wheel out back.
Thanks for sharing man!
I built a two wheeler a while back out of 2x2's and x4's(lol) that ones doubled as a bike hauler, Over here
, and a couple of other members shared their trailers towards the end of the thread. (its short)
There's nothing a little creativity can't do eh?
