Water ... Where from? Was the pump switch on? Did you find open valve? Is there a leak in plumbing? With full sink, was the faucet bumped open or did its valve fail?
Electric. Did converter get wet? It may have failed. If water sloshed as you drive, it could have splashed all over and shorted it out. Trace back from batteries as zigzagzui said. It is possible the main fuse or fusible link failed and protected your AS. If failure severe enough it may have also damaged your trailer grounding. Other wires may be damaged too. To isolate, remove power, check for shorts to ground then carefully add them back into circuit.
Insurance. Did you contact them? Can the dealer provide their professional estimate?
Bummer..hope you sort out soon.
