Generally with trailers, no electrical drawings were released to the public.
You mention breaker so generally breakers are 120V systems and fuses are used for 12V systems.
Lighting is typically all 12V.
So, knowing that we have isolated it down to 120V items.
So, check to see if you have 120V at all of the outlets.
Then check to see if any appliances that typically operate from 120V are working. Things like A/C, refrigerator and if equipped the water heater may have an auxiliary 120V heating element.
Not unusual for the water heater equipped with aux electrical heating element to have a damaged heating element if power is applied without water in the tank which creates a short.
RV fridge to operate on 120V uses a small 120V heating element mounted to the ammonia boiler that can short out.
The 12V side uses a 120V to 12V power supply (in RV industry it is called a "converter") that can go bad and can be directly wired to one of the breakers but with that you would not be able to charge the 12V battery or supply 12V to the lights without a battery.
