I have a Magnum 2812.
A Magnum 2812 inverter has a pass-through limit of 30 amps per leg, meaning you can utilize up to 60 amps total AC power by using both input lines (HOT 1 and HOT 2) to pass through the unit while also charging batteries; however, the exact configuration depends on how you wire the AC terminal block based on your power source and desired usage.
Let's just say that all 3 of your heaters were drawing the max of their 1800 watts, and your micro drew 1800 watts. That is 15 amps per device. Totaling a potential max draw of 60 amps on one leg, twice what the Magnum would like.
My point is this, if one is going to use high wattage devices in the motorhome, plug them into circuits that are NOT on the inverter based circuits to prevent overloading the internal transfer switch of the inverter. I have to think that overloading the internal transfer of the inverter is not healthy for it in the long term.
