Sounds like the campground pedestal may be OFF LINE. It also has a 30A Breaker you may want to check... When you check breakers it is sometimes best to turn them off then turn them back on. Sometimes it is hard to see they have tripped.
If the 20A service is still working on the pedestal use an extension cord and a light run into the trailer to give you some light until daybreak...
Your trailer ceiling lights run off your battery so you may have to turn off a few things in the trailer to be able to last the night... The furnace blower will eat up battery real real quick...
Good campers always have good PLAn Bs... We work hard at our PLAN Bs just for occasions like this...
Flashlights and candles perhaps...
