Sterilite, 40 Gal./151 L Wheeled Industrial Tote, Black, Case of 2

I have been using these totes for various different purposes for a few years now. We started using them when we began tent camping, and since I discovered them use them for all sorts of things. They are very sturdy, and the wheels/handle is a great feature. When we were tent camping that made them perfect, because that meant my wife could wheel them around also, instead of only me being able to man handle them. When we sold our house I packed a lot of things up in them, made it super easy to wheel my heavier tools and whatnot from my shop onto my tilting trailer and into the storage building. I've used them to bring tools to a job site and rest materials and whatnot on top of them as a sort of makeshift table.
I'm not using any right now for camper things, but our trailer has a ton of storage built in.
