When I bought my 2012 F350 DRW CC I had the option of choosing different GVW's on the registration form. The lowest is 10K lbs. and is cheapest. The highest was 14K lbs. The paperwork guy could not explain what this meant to me so I just chose the 10K amount which was quite a bit less. I assume that if I am pulled over and the officer cares, I could get a fine for being over the registration weight. Once I get the camper I'll look into changing this but for now I'm not going to be over that weight anyway. My truck had the registration paid through October 2014 so I don't know what the amount will be, but it is registered commercial.
