Old school percolator on the stove takes care of morning coffee for my wife. Though I could use the inverter to run a Mr Coffee if we wanted to (2K inverter/440Ah batteries/270W solar).
Unless there is no breeze or humidity is high, simply opening up the windows keeps camper cool enough for us on a quick lunch stop. Sometimes we do need to kick on the roof fans. The inverter will also handle nuking a snack.
While I haven't actually tested it, the AC is able to be powered by the inverter as well and it only draws about 8A in high (100ish DCA) so theoretically I could have the AC cool us down a bit for the lunch break as well.
Not everything needs $4Kish of LOUD generator power as part of the answer. I know the 4K Microlight on my 28' Bounder could be heard easily inside the coach, so I hate to think how much more annoying it would be in a TC.
