I have used one of these boxes as a top box, it is big, 60l, I will use it for clothing on a trip, to keep the weight down, and throw over panels for the heavier items.
it looks bloody massive, but after some test riding in today's blustery winds I will persevere, it was noticeable in a side wind, but nothing alarming.
I did reinforce the base, and fabricate secure mountings that I can undo in a matter of a minute or two, and added some cleats and elastic rope to the lid, not that I plan to mount much there!
Anyway I thought I would share a pic for ridicule, and testing is ongoing as I have a smaller one if it proves too much.
