What are your yearly registration costs for your truck?

I have the truck registered for 23,000 lbs., you license by GCW in Missouri, and it runs around $100 per year. It would be cheaper if I went to a lower weight, but 23,000 lb. makes me legal. And we did have a trooper check us when he stopped us for expired tag. It wasn't expired, I just hadn't put it on. Oops. He said he might have called DOT if we had 12,000 lb. tag on our longbed dually and 40' toyhauler. :)
