I lived with a single Coleman Mach 3 power saver in my previous class A motorhome. Typically amperage draw is 12 amps. In very hot temps, 110 degrees (concrete pad, no trees in Tulsa, OK in July) and I never saw more than 13 amp draw. If you are traveling down the road you would probably not have anything running but the A/Cs. If you were worried about the converter drawing power, you could throw the circuit breaker and depend on the engine alternator to keep the batteries up.
