Check the battery connections - Positive, negative, the negative ground.
Check the inline 30 amp fuse close to the battery, make sure its seated all the way.
Check the circuit breaker panel inside the trailer, makes sure all breakers are on.
Check the fuse panel inside, make sure all fuses are good there to.
If all that checks out, and still nothing, I would not know without more information.
