Abstract: A verge post having a plurality of flat vertical side faces and side edges for marking road verges or the boundaries of traffic lanes. The post is constructed with material which will fluoresce when illuminated with ultraviolet light, and to transmit visible light from the side faces and edges in two or more directions when illuminated with ultraviolet light from one direction. Different parts of the post can be made so they will fluoresce with different colors when illuminated with ultraviolet light.

Abstract: To provide needed stability between a vehicle, such as a pick up truck, and an added removable body component, such as a camper, one or more large inflatable structural components are positioned fully between them at the cab location. For example, wherein a large camper is placed on a pick up truck and the camper has a cab-over portion generally housing a sleeping space, two inflatable structural components are utilized. One structural component is located fully on the cab roof and inflated into mutual contact with the cab-over portion of the camper that is directly opposite the full cab roof; the other structural component is located between the full rear of the cab, minus any window area, and the front wall of the camper, minus any window area, and is inflated into mutual contact with their respective surfaces.
