Roof splitter...better front end aerodynamics
Big beliver here of DIY aerodynamics. The "pocket" in-between your TRUCK cab and camper cab-over is a huge source of drag and wind noise. Its like towing a parachute. A roof "splitter" will low...

Aerodynamics is an under explored topic. We could use more experimental here.
Since I have a late model truck with an older camper, I needed a spacer to clear the cab and bed rails. Not exactly sure how high to go, I built my first spacer with 1x6's sandwiched between 3/8" plywood.
I've since replaced the spacer with one two inches shorter made of 2x4's and plywood. On my last two trips (990 miles and 485 miles), I averaged 14.6 mpg. Typically, I've been getting 13.2-13.3 mpg.
Less wind resistance?
I'd like to try a roof wedgie, but am reluctant to risk scratching the truck's paint.
Keep those ideas coming.......
