I know this is a old tread , but we just got back from Florida. We have a 2008 Dodge Dually 4x4 CTD with exhast brake. We pull a Bighorn 3670RL with a hitch on the back connected to a pace 10 foot cargo trailer,with a 2004 Goldwing 1800 in it.It pulls very well, no weaving in and out of lanes and we have a camera on the back trailer at all times just in cause. We are at 70 feet long and did not have any problems what so ever, will you or could you, yes it all depends on the guy who sees you and is going to make a point. I try to stay in the low key situation and don't do anything stupid. However as the wife says it can't last forever, we'll see.None
