It does. Thanks

He dont know he is just a truck driver, now if you asked him a quesiton about food you would already have your answer

Mainly for gas mileage. it keeps the air from gettin under the trailer where there is a lot of stuff underneath to cause a turbulance. It helps the trailer flow through clean air. Less Drag. Just like the fender skirts and air dams on a Nascar.

X2 and they are junk. First tire tread on big road debrie you hit. Dented,bent,tore off. Junk in my opion

Thanks guys, good perspective.

They do help fuel economy but like Big H said they stay tore up so it appears to me any savings would be offset bymaintaince expense.
