It wouldn't take a lot of mechanical know-how to take a few of them (maybe two, they look wide enough) and put something inside the hole of the container to accomodate axles that would rig up a little push-cart.

Or maybe one of the q-drums as a front wheel, with two wheelbarrow wheels for the rear ones?

I just wouldn't put anything too heavy in there, considering it's not a real rubber tire. Maybe some food and blankets in there in order to consolidate trips.
