Based on what you described it doesn't sound like a bad fuse that is your issue. It sounds like you have a bad ground on that side of the trailer which is taking out all of the light circuits. I would recommend going over the wiring looking for any cuts or exposed sections and fix as needed. Starting with the ground circuit of the light as that's the common circuit that the turn signal and running light would have.
