1) Level front
2) Better sound system
3) Lower gearing

 

I would pay the extra and get the HEMI. Most of the other things are in my signature...lol.

 

I would get rid of the plastic chrome covers on the 20" wheels. Its true that the added chrome compliments the truck, especially in black, but they seem too cheap for a $40k truck. I would be willing to pay extra for polished 20" factory rims. A locking tailgate should be standard, and better factory tires. Those Goodyears really suck in pretty much any non dry road conditions. I also second the posts about leveling, angling the rear seats AND the 6.1L Hemi.
