One upper cabinet is used to store my undies, socks, bras, a few t-shirts, and PJs in packing cubes. My few sweaters are stored above the driving seat area. My third upper cabinet holds an extra blanket, sheets, pillow cases and a box for computer supplies.
I had a wall built behind my van seats, read why in my blog on stealth vanlife, which gives me wall space to hang a shoe rack and 2 command hooks for my rain jacket and shawl. The only two clothing items I have not used in the two years are a winter coat and winter boots, which are stored in a bin under my bed, just in case I need them. Lots of room for those so I keep them.
