If you have not used a cheat and are still taking damage on your travels use this trick to save money. When you get to your destination, sell your goods but do not buy any more until after you have been to the garage. When you enter the garage, exchange trailers and the new trailer will have no damage. If you want to get your old trailer back again, just change again and the damage will be gone. Note: If you have only sustained minor damage it will probably be a better value just to repair it.
