We opted for the factory installed inverter and transfer switch, the full insulation package including the under foam, and the manual awning.
The plug into a 12V socket inverters can provide up to 300 watts. Our 1500 watt inverter runs a vacuum cleaner, not the 10 minute run time chargeable, but the cord powered vacuum, 600 watts at full power. We use a 3 qt instant pot, 900 watts. The instant pot is a great addition to camping. We also have, but rarely use an instant kettle, 1200 watts. The instant kettle heats water in half to 1/3 the time of the tiny burner heads on the propane cooktop. If we are in steady sun, the instant kettle is used. We do pour over melita coffee.
We only have owned our Escape for 7 months, 12,000 miles, and over 140 days camping. We never plug in, except 2 afternoons in FL when we ran the A.C. for a couple hours both days. We always boondock, even in developed campgrounds. We have all the comforts of home, plenty of power for conveniences, and so far have been toasty warm at 20°F. Awning? We tend to be travelers rather than campers. In Mexico, when staying in a spot for a week it was manually deployed. In the PacNW this week, are you kidding it is raining buckets!
