Sweaterdors are NOT necessarily the flat, slide-under-the-bed type containers. This is a 90 Qt Sterilte box that I use along with a couple of Rubbermaids the same size. I have a total of six of these. The only option I could realisticly go to to upgrade is a walk-in, as conventional humis to hold all these would bankrupt me.
I'm p[osting this to show what a sweaterdor can be besides a relitively low volume flat box. These are close to the capacity of a 101qt marine cooler, and cost less that $10
