My sube. its got a goofy rack rail right on the edge of one of the roof, and another tough rail on the other end, 2 front tires look like they are peeking out of the wells...
14.6 feet long.
hearing the front rail whistling through the wind at speed...there is ZERO difference in the high 30s mpg..connected to the roof or not. it just deletes a whistle of slight strain...
is the quest for aerodynamics lack of power for the given body?
even 120mph is not quite like the space shuttle, and that has goofy pieces of foam getting tortured on leading edges...
I flew on old planes, every rivet straining. I think aerodynamics is a hoax. our goal is to defy air and stay on earth...and even utilizing it through our grills to keep an engine running cool.
I am just trying an argument. My dads rig? 13 foot 6 loaded or not, it doesn't care about wind either...at 65 feet long 26 tons or 50. it just doesn't matter. my old sube at 2750 pounds on 1781cc doesn't care either. I conclude..it is weak drivetrains driving people into aerodynamics.
I just don't see why...we have weak drivetrains.
