Don, ball diameter is in direct corelation to trailer size/weight.
1 7/8" is what you require for your light load.
I did not notice chain stays on your hitch (yet?)
Required by law in alot of places.
Also for your trailer you can get a pivot on the tongue for lateral movement of the trailer, so it can move independently
from the bike on the longitudal axis. This is common on better quality motorcycle trailers. BTW the longer the trailer tonque the better the stability at speed, as opposed to being too short.
