This was my hangout for a week at Burningman. It was basically a 4′x4′x4′ coroplastic box.
The flutted plastic sheeting was nailed to 2×2′s in each corner. The large door swung up to serve as a sun shade, and sealed tight to keep the dust storms at bay. When this happened I’d watch things blow by through the bubble window.

Inside was the cooler, lights and shelves for the radio, fan, books and misc. amenities. I slept in the back of my truck. Yes, that’s a real recliner in there. My nick name was Jack. I was Jack in the box.
This design led to the development of my bicycle camper that I built the following year.
