Also fits the car...
Serves as a small, inconspicuous ventilation when the van is used as a camper. A skylight was out of the question because of the appearance, the lower stability and the size and height. The mushroom fan with an outer diameter of 150mm fits exactly on the base of the same size on the Sprinter 906. The plastic versions were too big and too sensitive for me if you come into contact with branches. The only thing annoying when closed is the toggle that protrudes deep into the room. But if the roof is covered on the inside, that shouldn't bother either. Solid workmanship, gross motorists should treat the T-handle with screw locking or a flat lock nut -)
