Truck cap window propped open
 
Did you Know

According to this link I lost mpg when I put my truck cap on. Would propping the rear window open help me get some of it back? Today I tried aba testing with my scan guage but the numbers were all over the place being windy out. Check out the photo.

No. Not measurably.

Your flush cap has converted your pickup into the aero equivalent of a van or large SUV (Suburban, Excursion).

I would have expected that you would pick up about 5% Mpg with the cap.
