Towing Problem

Hi all! I traded my Bravada in for a 2000 Durango 5.9 4x4. I hooked up my boat and the tail lights don't work on the boat. The turn signals, brakes and hazards work, but no parking, or running lights on the boat. Everything the truck works. Is there a seperate fuse box for towing somewhere? Fords are like that. Any clues? Thanks!

That's an odd issue, hopefully someone here can chime in and answer that for you. I had an 05 Durango once but never had that problem before.
