Wholly unworthy of this thread, but here she is. A truk kiddie trailer I got at a garage sale for 40 bucks. It was set up in stroller mode and the guy threw away the shaft.

Sooo, I used an old weed eater shaft as suggested by someone in this sub forum way back when. As you can see it puts a lot of weight on the hitch. (too much, it seems to me) Still, no probs so far. I just cut out the seat and slapped down a stiff piece of plastic for the floor. As ugly as it is, it keeps the groceries dry and the cars on edge.

I've carried a propane tank and countless groceries including a fat watermelon and a bunch of 2 ltr. bottles. I wonder if there's a way to shift some of the weight to the rear.
