Is your RV 50 amp? If so the park pedestal may have lost one leg of that circuit thereby shutting down 1/2 of your RV.
If you don't have a surge protector/EMS, hardwired or portable, I'd recommend getting one ASAP & use EVERY TIME you plug in anywhere, it would've caught this problem & shut it down to prevent damage to your rv. Yes they are pricey, but so is replacing the fridge, water heater, TV's or any of the electronics onboard.
There's 2 items that should be mandatory for every RV, #1 the surge protector & #2 a true adjustable water pressure regulator to connect at the incoming faucet.
