wow... thats awesome! that you're getting 13-18

I never really pay that much attention to my MPG. I really don't think the shell makes any difference since it would just extend the air flow that is already being pushed over the cab. If I was to guess I say the shell would make the air stream smoother increasing MPG. I'm sure the lights and rack do make a bit of a drop in MPG.

My average MPG goes between 13 -18 hwy (according to my edge tuner) but I have 4.56 gears, 37's, tuner, cai, and cat back exhaust. I compared it a long while back and it was pretty close to actual. If I stay off the pedal 15-16 is easy to maintain.

Impact, did you notice any decrease or even increase in gas mileage with your shell over the bed? and do you know how the rack etc. played into gas mileage. Currently Im running 315s with 3.73 gears and nothing in the bed and get ~14.3 mpg

That's alright. Thank you very much for the info!

sorry i didn't see your first post. The guard is a T&H. I think I got it from autoanything.com

Hey Impact, what kinda grill guard did you have on before the boondock? Im trying to find one exactly like that for my truck

Hey Impact, who manufactured that grill guard you had on your old setup? when you just had the level kit and the PC 35s... I really like that and would love to get one if I can find it. Thanks!
