I just finished towing my boat from Baltimore to Cape Charles and back and the bow of the boat is full of nicks from road gravel. I do not want to permanently mount mudflaps to my truck and I am thinking about buying a set of hitch-mounted mudflaps to protect the boat when it is being towed. I would like to hear thoughts about this from anyone who is using them. Do the flaps really work? Have you had any issues with them? Other thoughts? Thanks.
