When flat-towing a dinghy vehicle, it’s important your motorhome has a mud flap that works. Some of the loose-bristle or brush-type flaps seem to reach a horizontal position when the motorhome is traveling at highway speeds. My solution was to attach a long piece of 1¼-inch galvanized pipe hung with some light chain to the flap to help keep it in place.
