FWIW, Florida has a POSTED speed limit of 70 mph on a great many miles of its interstate highways. BUT, there IS a lesser known law that states 65 MPH for vehicles towing. Big rigs? Pickups? Autos? Motorhomes? Is it enforced? Where? When? Why or Why NOT? I do not know, but "ignorance of the law" is not a legal defense here.
I forget where I found it, but have seen it. It isn't posted, but it is a law. I still pull my bike trailer at 70 anyway, as I have NEVER heard of it being enforced. My choice to take that chance. But as heavy as my TT is, I pull it at 65 or LESS to help with fuel consumption that comes with speed.
As to the question of DOT check points - there is a sign at the US 17 Florida/Georgia border that states 'ALL Pick ups and trailers MUST STOP'. I have pulled in when towing my enclosed bike trailer just to be sure. They actually asked me "Whats inside?" I said my bike. They waived me on.
They have waived me on when NOT towing - even before I could come to a complete stop. Now, since I don't have a topper or agriculture products, I don't bother pulling in anymore unless towing an enclosed trailer.
