Thanks! I like this trailer a lot. Yeah, the loops allow for various net configurations inside the box, I have two small bicycle nets and two large motorcycle nets. For example, when I went grocery shopping I stuffed smaller, but denser/heavier items (bottles, cans, apples, etc) inside the side nets and soft or delicate items (bread, eggs, bananas) by themselves in the box so they wouldn't get smacked around and squashed by the heavier items. I got that idea from um... car cargo nets. Plus, you can put more stuff on the top using a larger net or bungee cords, I used that with a pack of paper towels, for example.

Yeah, it's very stable, I tried to flip the trailer hard by making sharp turns on loading ramps, going off tall sidewalks at an angle. I believe that with center gravity this low it is impossible to flip this trailer under normal use. I got it to skid and jack-knife once on wet surface but I really tried very hard to do that.

One more thing: those boxes are securely stackable (the bottom sits inside the sunken area of the lid so it won't slide off). I imagine it would be easy to secure another one the top with a pair of cam straps or even bungee cords. Of course, you'd have to keep one on the top loaded with lighter stuff.

Oh, and I didn't mention, but it's kind of obvious, that these boxes are completely waterproof.
