We were pulled for going too slow if you can imagine that! The guy didn't even mention commercial operator/ non commercial. From what I have read on this site South Dakota allows 75 foot rigs as does Montana and Wyoming. Interestingly just got off the phone with a bud who drives a coach for NASCAR and he says about the same thing you do if you don't attract attention you are cool. He did say California is bad and Texas can be bad as well about over length. He mentioned something interesting to me anyway he said that I should stop at agricultural inspection sites in Florida. He said it's no big deal, they don't weigh you they are just making sure that you don't have any agricultural products that could damage Florida's farms. To be honest I haven't stopped in 3 round trips to Florida and back and nothing has happened. Can you shed any light on that? Thanks.......JR
