This saddens me. Going for the look that was not intended for a truck is going to cost more money in the long run. Not only are you spending money on a lift kit, leveling kit, big tires, probably rims too, then you need a gear change or motor upgrade to offset the "look". When you could just level it out, throw on some clean wheels and tires close to stock size and not have to do SO many other things. Or you could get rid of that one and get one that was built to have the look. Either way, you will never get the mpg you're getting now.
I would put a cold air intake on it if i was you.
