You can find a bazillion different hitch plugs just about anywhere you look. I got one off of eBay that's a Harley bar & shield with wings that's cut from a solid piece of billet....pretty slick, and I've never seen another like it.
One of my favorites is one I saw at Gander Mountain...it was an electronic (hooked up to your trailer power connector). It was a cartoon Buck sitting on the hitch, and when you used your blinkers, the deer pointed in that direction, and when you but on the brakes, he put both hands over his eyes!. It was a real hoot.
BTW... don't forget to get a pair of those big chrome balls to hang under it
