Hi MrWizard,
Here is what I mean.
Power source-->converter-->battery bank-->inverter-->RV shore power cord.
Lossy as the very old dickens for the converter is in this case 0.7 power factor, and the inverter might be 87%, but it does prevent overloading a 15 amp circuit. And if the inverter is big enough you can, on a temporary basis draw more than the output of the converter.

Don do you mean two chargers when you say double conversion?
Because most of the time when that term is used it is in refernce to an inverter trying to run a converter and no shore power
Because I am Not talking about that or ac to DC to ac
Also check out TrippLite they have psw inverters
