So tonight I decided to try and lighten the hitch a bit.....
I know it does not REALLY lighten it much, but it does make it LOOK lighter :cool:
I also worked on the bottom contact point of the rack, down near the rear axle, I was not satisfied with the way it was.....

Not much beef there, and I thought it should be a bit stouter.
Taking it right off the axle was not really an option, because of this flange that the frame has....

Kind of hard to work around that
This is what I came up with (on the other side, I still have the left side to build).......

I missed ever so slightly on the arc of the bottom piece, I wish it would have matched perfectly, I might just pull it off and weld some on the edge and then grind/file it back some

This way I'm using the fender mount as well as the rack mount, more beef too, so I think it should be able to handle more stress.
Again I'll say I know it is a lot of steel to be hauling around, but the trailer weighs 23Kg alone and the beer often weighs well over 60Kg so another 3 or 4 Kg really is not going to make a difference, I'm not trying to win races, or go touring with this set up, this bike is a work bike, it is for hauling a trailer full of beer around
Cheers!
