Being a huge Star Wars fan myself, I have to admit that the name Rebel was a big plus when I picked out my truck. Especially when I was checking it out online and found a pic of a tailgate that had Tie fighter kills next to the Rebel badge. Not surprised at all by this promo, very cool.
I've had billitbadges.com make me a few custom badges before. Emailed them a week ago to see if they can make me a "Rebel Scum" badge in the same font style as the existing Rebel badge. It's a pretty cool service, you email them pictures and dimensions and they make a custom one-off billeted badge. I'll let you all know how it turns out and how much it is.
