We plugged the 'shore' power in and all lights work. Converter fan runs fine. Receptacles also work fine.
After looking over the tongue wiring some more there is definitely something wrong.
The battery leads look good. The red has a 20A fuse and the white connects straight to the trailer frame as ground/negative.
I am guessing the issue may have to be with the wiring from the trailer tongue to the tow vehicle. Although I am a bit confused why that would prevent the battery from powering the 12VDC system on the trailer.
There is a 5 pin rectangle plug on the trailer. It is connected to a flat 4 pin connector for the tow vehicle. I peeled off all the electrical tape and found this:
Tow Vehicle -> Trailer
White to White
Brown to Green
Yellow to Red
Green to Brown
The thick red wire from the 5 pin rectangle connector does not connect to anything. What should that connect to?
Looks like some on has fudged things around a bit
Have you tried a separate ground from the battery right to the trailer?
Red wire could have been used as a charge wire for the battery from the tow vehicle.
Do all stop, turn and tail lights work properly?
