If you are going to travel over salt laden roads, make sure you wash your trailer and frame once you get out of the cold and salt. I had a friend who pulled back from Texas to Missouri one spring and had to drive on roads which salt had been spread. His frame broke out with small rust marks all over. All areas where the paint had been dinged by rocks or was thin. It was pretty surprising. It looked like the trailer frame had a case of the measles.
