Homemade sleeping pod on standard little trailer 8 foot trailer; I have the trailer title. It has screened windows on each side, and a screened ceiling vent. It's just a foam pad bed with a shelf on wheels. No electric inside it, but small string of AA powered xmas lights are enough to light it, and it stays warm because it's sealed very tight with the windows closed. The brake and turn lights worked when hooked to my Subaru with the trailer plug. I bought it last year with fresh gray paint, but the previous owner obviously didn't prime it, because now it's starting to peel. It weighs 640 pounds.
