Roger,
We mounted our Inverter, a PD 30 (?) under the couch on the driver's side, because it's not really usable space tucked in behind the bathroom. We put an outlet there to plug it in the inverter. We put it in the front because it's a short run to the batteries, close to the
solar panel. As well we mounted a 1200 watt inverter next to it (short run again to battery).
The reality is we never use the 1200 watt inverter. We use the cigarette lighter inverters to run AC devices, like chargers, TV and Sat dish.
We have added four 12 volt outlets, one under the dinette, one near the couch, one in the outside
fridge compartment and one over the stove side counter. We use the outside ones for our air compressor. Inside we use one for our wi-fi hot spot.
Our Chromebook computer can be recharged directly from 12 volts.
We have tons of AC outlets, I think 10, 1 outside and 9 inside. 2 are on the face of the dinette with USB chargers, 1 at the back of the dinette, 1 under the sink for the hot water heater and air conditioner, 2 under the couch, 2 in the ends of the counters, 1 in the
fridge compartment and 1 outside near and under the rear of the
Scamp. Our Scamp came with 4 AC outlets as I recall.
Yes I did do
electrical engineering in a couple of careers.
