I mounted a large toolbox (Craftsman 24.25" x 9.5" x 9.5" steel toolbox) over one of the wheel wells in the rear to add secured storage. I wanted to be able to secure a variety of tools in the rear of the H2 without wasting space the main cargo area. Over the driver-side rear wheel well seemed like a perfect area as there are anchor points on the frame where the original interior spare tire carrier was mounted. These served as excellent mounting points for a metal bracket to hold the toolbox.
