I Have An 05 Power Stroke An Have A Problem With Running Lights On Trailers. I Pull 4 Different Trailers With All Lights But The Running Lights Working On Each Trailer. I Have Re-placed The Fuse For The Lights At Lease 5 Times. Obviously, I Have A Short Somewhere But Haven't Been Able To Find It. A Friend Has Basically The Same Truck In An 06 Model And He Has The Same Problem. Ford Says There Is No Problem. Any Ideals???

are you using an adapter from camper to round if so the adapter may need to be rewired to match the trailer.

When do you blow the fuse? Sounds like you have a problem with the wiring on one or more of the trailers.

I agree fix the trailer(s) wiring. With two trucks blowing fuses and I believe both those models have the truck plug that has both the 7-pin RV and a 4-wire flat plug on the assembly which would eliminate a bad adapter.
