I recently found a used 4x8 trailer on marketplace. My plan was to build a small camper but it turns out an acquaintance needed a Teardrop camper to display her products at local farm markets. I am building it like I would a standard camper, I'm just doing a custom galley based on her needs and leaving the inside natural. She could toss in a mattress and camp if she wanted to. The camper is powered with a small Jackery.
