Here's my take on Sleepy's airfoil/ deflector. I made it "pointy" with a 30 degree sweep back. It uses the same gutter guard as Sleepy's, but is framed using 1x2" lumber and aluminum angle stock. Also, capped the corners with aluminium. Suprisingly light at 4 lbs.

Very nice work.
I can see you are very much a perfectionist.
If you would be so kind to explain
What is the goal and outcome of such a device?
not sure I see any advantage for an "airfoil" effect.
minimal to no increase of aerodynamics at 55-60mph

It is more to keep bugs from splattering all over the bulkhead of the camper behind the truck cab, atleast that is why I built it. A few people on this forum have also reported a small increase in mpg. .

Nice job... good to see your thinking cap on. Have you tried it over the road yet.
When the bugs are gone so is the catchers mitt effect that the area between the cabover and truck has... your drag (cd) will be reduced.
The thread on the original airfoil is available in the tc university click here for those people that voice opinions without trying to understand how it works.

Nice work! FWIW: I'd have set it up with the "point" just to the rear of the windscreen top...and made it solid. Also, just about anything that smooths the airflow helps at ANY speed. My deflector pays back 2-3 mpg depending on conditions---I figure that saved me about $400-$450 on my last R-T to SoCal with the TH.

Nope, haven't tried it on the road yet, I can't wait to see how it works. Thanks for the kudos and the inspiration to make it!

Thanks! Ya, I was thinking about putting it further back when I was mounting it. I was worried about roof clearance and hitting my head on the outer edge when entering/exiting the truck. As it turns out, it would have cleared the roof by a couple of inches. I hope it atleast makes a modest difference in bug mess and mpg. If nothing else it was fun to make!

What opinion? I was simply asking what the goal and outcome was.
don't be such a curmudgeon!!!
you could have just said it was to help with (goal)bugs and (outcome) was less bugs and better fuel economy.
Please understand I have not seen this topic in the TC University.

What did you use to attach it to the overhang and did you seal for water? Good looking job. You could put your "handle" on it, or put RV.NET" on it.

I replaced some pre-existing screws with some slightly larger lag screws and washers. Between the camper and deflector there is a strip of the foam seal you put between a truck bed cap and the bed rails.
