Yet another Air Dam/Spoiler/Airfoil thingy
Since we don't have enough threads on this already: I decided to make one, the goal was to reduce wind noise which was more with the camper on than off. Also wanted to reduce the bug count on the c...

The air trapped between the camper and roof of the truck forms a dead zone that effectively blocks the flow of air. This is easy to see. Drive through a rainstorm. The nose of the camper and the overhang area will be wet. A few inches behind the roof of the truck to the bed area will be dry. The same can be seen driving through an insect hatch. There will be no bugs in that area.
Maybe on your camper, but provably not true on mine. Bottom of the overhang will be wet and is spattered with bugs. There is a line of bugs on the camper bulkhead and it will be wet in the rain. Opening the rear window resulted in a large wind through the cab. Air flow in the area is much different after installing the dam.
Any universal statements like that have to be treated with skepticism. Campers and trucks come in a wide variety, the spacing between the cab and overhang will differ, the overhang may end in front or behind the windshield depending on crew cab vs short cab, EW vs. NS bed, etc. Not quite an infinite variety but approaching that. Which also makes the design and installation of one problematic, others experience's may not be duplicable on your rig. I'm not suggesting what I did would work for others, but I am contributing to the knowledge pool.
