Here are some pics.
So far I like the wings a lot...the seem to really clean up the air flow in the open position and help reduce the effect of truck turbulence....at least it appears that way from my preliminary observations. They definietly help cool the legs and upper body, even at 20 to 30 mph.
Closed they provide a lot of warmth from the engine heat....close them on a hot day like today was and you will fry your legs.
This is all subjective opinion though....you would need a wind tunnel test to verify it all....but I guess the bottom line is whether or not the customer is happy.....and I am, would buy them again without a blink.
