greetings from Texas...............
 

1st post.
what got me interested is the aerodynamic articles I came across while i was searching the web. i was amazed at the skills and ingenuity some of the post had especially MetroMPG's
i have a 1 ton, 4 door, diesel Chevy truck that i am in the process of making an aerobed for to improve mileage while not carrying a load. am not finished w/ it yet so can't say if it has helped or hurt.
when i get a chance I will post some pics.
