I doubt anyone will have a diagram. You're best bet is someone who actually has one chiming in about what he's got.
I looked at what pics I could find at a number of dealers websites and I don't see anything that looks like a 110VAC outlet. There is a 12VDC power outlet on the front console that you could plug a small inverter into. I've never had a MH, so I don't know if this power outlet is only powered from the chassis battery or the house battery/converter. (I suspect the chassis battery; and it could be off with the engine off, too.)
