Abstract: This invention is a hard sided pop-up truck camper that fits on an ordinary pickup truck. When folded down, it looks like a typical pickup truck topper and will allow the truck to fit into a garage. The folding sides take up less than 6 inches of height when folded which maximizes its use as a topper for hauling while also maximizing the vertical height when erected so it can be used as a camper. When erected, it allows a person to stand upright throughout the inside of the camper. Current hard sided pop-up truck campers are designed to extend by raising straight up mechanically, the sides do not fold down upon themselves like this invention does. Also, current hard sided pop-up truck campers in the down position typically extend above the cab of the truck making them too high to fit through a garage door.
