Certainly one of the worst time's to break down while towing your boat. Had it happen to me couple times. On the boat stud bolts broke off and there went the wheel,boat had to be tow in on flat bed. Another time my truck broke down fuel pump went out another bad experience. Like someone mention try to have some extra parts with you and the tools you need to fixed some of the problems. One of the best things to have is a cell phone. If you break down and have to leave truck and boat,people will robbed you blind.
