Am I missing a bad fuse on the truck? #6 on the fuse block
is for the trailer wiring and it is a good 20 amp fuse.
#37 is for trailer parking lights and that fuse is good too.
Open to comments and opinions.

Is there power at the brown wire when the lights are on? They most likely have a relay somewhere to insulate the regular circuit.
