Driving and towing are different.When driving you are just parting the air as you go.When being towed the buffeting from the tow vehicle is tremendous.i saw the top on a 30 roadster partially shredded after being towed at 50 MPH for four hours.Air can only jump 30 inches behind a vehicle after being parted by that vehicle.at the 30 inch point it goes violently turbulent.At some point,I'm thinking 18 feet after the trailer load,it goes back to a straight wind,but not turbulent.That was some of the stuff I had to learn to haul lumber,sheetrock,etc and how to tarp it.
