I'd call Monaco at 877-466-6226 with the last six of your Vin #. They can probably Email you a wiring diagram of your inverter/charger system that a 97 Dynasty should have as standard equipment. You probably have a large black box on the ceiling of one of your bays with battery cables going to it. You need to learn where it is as it has two 120V breakers on it that will solve many of your 120V power out problems... microwave and TVs. You also need to find the GFI outlets (kitchen or bath) and reset them first when having 120V problems.
I would leave the inverter off when hooked to shore power, otherwise you may not know when you loose shore power as the inverter may power up so fast you do not even loose the TV's picture... resulting in dead batteries the next day unless you notice some of the 120V outlets no longer work.
While the inverter will run the microwave and make coffee, they draw so many amps that I crank the generator when they are used. When boondocking the batteries need charging for 1-2 hours/day so you need to crank the generator anyway.
Should be a lot of MH for less than $40K.
