For light loads, I just have a used Burley kid's trailer (plus a spare trailer). Good for up to about 100 pounds or so. The first one I stripped the side covers off. My current trailer, I use open-top, but with sides to protect the wheels, and a small amount of material left on the front and back so I don't have to secure the load.

I do have a homebuilt trailer that I use for the heavy stuff. It got pressed into service before being 100% complete. The capacity is about 500 pounds, more or less, or about the max I can pull up my local hills.



My trailer is a direct pull-behind with a straight tongue (which means it only works with my cargo bike). I used a Hiem joint on the trailer and a bolt as a pin hitch on the bike. I suppose I would look for something that had slightly more rotation if I was replacing the hitch.
