Sandwich panel caravan 7 cm with 6 mm bent sheet metal corners, with a three-layer caravan door. Dimensions: 6 * 2.70 * 270. I made it by hand myself and did not finish it due to lack of funds. You can complete it with solar power and interior furnishing. I had established a room, a bathroom, and a kitchen at the front. Made from the best materials and a luxurious item, to say the least. But I could no longer complete it. It cost me around 14,000 riyals, including a sofa that converts to a bed and a door handle for the stairs. It needs window cutting and installation, and interior insulation after electrical and drainage installations.
