Power converter (smoked/fried)

That's pretty wild that water could get in there. They're usually pretty protected from water. I've always found that pressure washing an RV is a bad idea anyway. RV's aren't made like cars and the high pressure water does a good job of removing and getting behind the various sealants used on an RV. Not to mention infiltration thru windows and other vents. Looks like some water may have found it's way in thru the power cord opening.
