I use a Ford Ranger as a dinghy vehicle with my Class C motorhome. I found that items I carried in the bed of the pickup slid to the front during transit. To solve the problem, at no cost, I took the light cones off an old pole lamp and cut the pole to fit across the truck bed. The spring-loaded mechanism holds the pole in place and works as a good solution to keep boxes of tools, firewood or other items secured in the back of the truck. They can also be easily accessed when the tailgate is open.
