Bart,
Did you ever do this mod?
I just worked the math & if you install a 2KW inverter and assume 90% efficiency (typical for Modified Sine Wave (MSW) units), you'll be drawing 185 Amps at max power. That's a lot of juice to run through a 12' cable.
I'm working on something similar on the Coachman & started a new thread on the topic.
