    Hey guys. I had a serious lighbulb moment the other day. Ok im pretty sure you all know that trucks get very poor MPG mainly because, Well their trucks, but not only that but because since their higher off the ground than most of these other cars, the wind catches on everything under the body and frame. Well i remember seeing where people would make full undercarriage protection for off road use to protect their components from catching on rocks by coving the entire underbody and frame with metal plating. Thats when it happened. What if i were to cover the ENTIRE underbody of my truck where possible with diamond metal plating so air can just flow smoothly under and out the back and not catch everything causing drag. Does it sound like a good idea? Has anyone ever tried it? With gas prices sky-rocketing these days i would like the save a tad bit of $$ at the pump

    Seems like a lot of work, not sure if it will be worth it or if it will make a difference.

    How much would the plating cost though, I say we all just start a GMTC gas station where members get good prices and we all share the profits. Lol

    Well my local lowes sells 2x5 foot pieces for 76$ a piece. I know its a total ripoff. I might end up going to a scrap/junk yard and getting some for the cheap and clean them up. And LOL thats a good idea XD

    How much added weight will that add to the truck? Added weight = lower MPG.

    Also alot of the issue has to do with the truck just being higher off the ground and for the older trucks having the aerodynamics of a wall. wide tires made a difference as well as the weight of the tires since it is increasing the rotational mass. Next just keeping up on a tune up will help a ton. The 5.7L vortec was efficent but nothing compared to the 1999 up vortecs. The truck is heavy also and there really isnt a way to help that out.
    But hey give it a whirle and let us know the results.

    Also just having the front rubber air dam in place will help milage since the wind tunnel testing is what caused that to be put there to reduce drag. and just rember you will still have a large air bubble to pull behind the truck no matter what as well.
