A couple weeks ago I was surfing Ecomodder and read a post about potential ecomods to semi's and tractor trailers.
Then last week I was up in around the St. Louis area when across the divided hwy in the on coming lane I see this semi going north on 44 with what looked like a trailer skirt on the bottom of his trailer he was pulling.
It looked like a flat piece of material that stretched from the back of the tractor's wheels all the way back to the rear wheels of the trailer. The back of it was cut in a half circle against the rear wheels and it hung about 6" off the hwy. There was one on both sides of the trailer.
I thought it was kinda cool. Anyone else see any trucking companies doing this? This is similar to what I saw -
