    Just wondering, does the roof spoilers make a difference?

    What about the "trailer skirts"?

    How about that weird thing attached to the rear of some trailers.

    The skirts work as well as "the weird thing on the tail".

    I have been dangerously close to the back of a truck with a "trailer tail" and the air is not anywhere near as turbulent as a trailer without a "tail".

    Pretty soon we will have 56 ft long boxes that are drop frames for more aerodynamics and 30ft pups!

    Just a rumor but the CEO of YRC is trying to push to make 30ft pups legal. Or is this a ploy to make 56 ft trailers not look as bad?

    I thought I read somewhere FedEx was pushing for double 30's on the Interstates.

    56s? Our yard is too small for 53s!

    I can't imagine 30' pups would be any different. Even pulling triples probably wouldn't matter. Who looks in the mirror anyways?
     
  12. A trucker friend of mine said that it helps with fuel mileage. He claims it helps in the event of tire blow outs too. The treads from the rear tires of the tractor hit the skirts and send them out the back rather than sideways. Whether or not that is true, I'm not really sure.

    Several companies have been pushing for 33 foot pups, including UPS.

    Its for aerodynamics. I get between 6 and 7 mpg. If it helps improve even a half mpg thats big money

    Pimped out with skirts and tail! I wonder if his trailer is eye candy to lot lizards.

    Yes on the fuel mileage. No on the tire deflection. The skirts are just fiberglass and if something sufficient hits them they come apart.
