Anyyone who is familiar please PM or post. My Mom just called me, they are supposed to be headed out for the weekend. Anyway, they bought this set-up and know little about RV'ing. Anyway, they are doing their pre-driving saftey check and they have no trailer brake lights or directionals. I know nothing about RV's but said it sounded like a fuse. Any other theories suggestions? I dont even know where the fuses are to tell them to check. The tow vehicle has lights. They have a Dodge 3500 dually.
