Can anyone recommend a heavy duty storage container that I can store my Anderson hitch in when not in use? I was using the box it came in but it broke. I don't like to leave my hitch in the receiver when not towing for a variety of reasons so I'm looking for heavy duty container of some sort to store it in. Prefer plastic or really heavy duty cardboard. Don't want wood or metal. I have some plastic containers that would work but they are all taller than I need so wasted space and take up a lot of space in storage.
