We will be having our first local diesel truck drag race here on June 24th. I am looking to remove a few non essential items to lighten her up. I only want to remove things that are somewhat easy like the spare tire and 2nd battery. I am wondering about the tailgate. Is this more essential for aerodynamic reasons to keep it on or will the benifit be greater (weight wise) with the removal of it? I also have 2wd drive, so is the tailgate weight more important for traction (hooking up)?
