Maybe Cosmic Sans MS in bold. That always seemed like a cool font to me. Contrasting colors would be cool...like black background and green font or blue font (goes with the truck) and a darker gray background..maybe throw a "4.7 Magnum" in there too? and maybe a few mods like you have in your sig.."Nitto Terra Grapplers, Angel Eyes w/ Eyelids, K&N Air Intake, 8000k HID's Heads/Fogs"
