2005 National Trailer Fuse Box Location

[fireman749]

Does anyone know where the trailer fuse box is located on a 2005 National Seabreeze RV? I have running lights and turn signals but no brake lights to my boat trailer. All the trailer lights work correctly when it is hooked up to my truck. I have checked all the fuses under the dash and they are all good. I have read several forums where most of the other brands have a separate fuse box for the trailer lights so I am trying to find out if anyone knows the location of it on my RV.

Thank you for your help.

A 2006 is in the bedroom in a panel under the sliding doors. Yours should be somewhere in that location
