Had 4" of power fall and decided to do an air flow test

these were taken after 2mi at 25 mph and 1mi at 45mph out side Anaconda, MT

notice the vortex patterns at the transition from horizontal to vertical

I only cleared the snow from the windshield, side windows and hood



these were taken near Wisdom, MT 10mi at 60mph
the first one shows the air attachment going to the tail in the horizontal plain and warping in in the back from vertical




a small disturbance behind the hinge other wise it looks like the "ladder rack" [part that protrudes above the cab ] dues not create much disturbance , as expected some but small. the air is steal able to stay attached

these were taken at Georgetown lake speeds of up to 70mph

this shows the termination past the tailgate after I built the canape I noticed that "ALL" the new trucked have a similar shape added to the top of the tailgate depending on the make from 2"-6" to help brake the vacuum bubble at the tailgate


and to show why a 2 piece canape. It's a truck its gotto be able to work. 30 70lbs bails of hay

so far I'm avraging 24mpgs on the flats with a 22mpg low and 27.9mpg all time high
