Anything up to 35 - 40 pounds and it tows rock solid with no handling vices or influence on the bike provided the load is as far forward in the box as practical. The further forward, and low, you can place the load the better it tows. At the sort of speeds a sane person would do, it's unaffected by mid-corner potholes.
As the weight of the load increases over 40lb the handling starts deteriorating. The most I've had on board was 65 pounds which was just dangerous at anything over fast walking pace. The further forward you keep the load the better it handles.

Nice work
As far as the handling characteristics, I think it could be improved by putting a bit of rearward tilt on the pivot. Because a one wheel trailer hitches to the bike in such a way that there is roll coupling, it seems intuitive to me that angling the pivot would create trail, and improve stability.
If you look at a BOB trailer, you will notice that there is a noticeable angle to the pivot, and I can say from my own experience that the BOB is very stable under all the conditions I have put it through.
