Hi Western,
I'd expect nothing less from a camp owner like you. You don't "low ball" anything for your guests. I hope they appreciate it.
I forgot about the two legs. That makes a 200 amp "look" like 400 amps (200 per leg) from the RV end.
I run my 30 amp rv all electric most of the time--but I've "cheated" by adding two auxiliary shore power cords (wired to code), one for the converter (20 amp) and one for the water heater (15 amp). I used a system of male and female plugs so I can switch back to OEM configuration in seconds.
I'll never be in the market for a "big rig", and mostly I boondock.
