A photo of my home built fibreglass folding trailer caravan. I copied the Portafold/Ansfold idea of folding. Size is 6ft x4ft base, with erected height (interior) of 6ft6inches. I built it to use with my Quantum kit car. It has a sitting area for during the day, converting to a double bed for night. Again all the boards used are GRP, with foam insulation.
