Multiple answers: I have been using the micto and fridge with the inverter for about 5 years now. I matched all the power requirements to the inverter before installing one. I would not try to run the window ac and micro at the same time.
No I don't have shock obsorbers on the ac. Monroematics? Joking :)
The Honda 1000 would handle the van ok. Already have an 8k for the house because we live in hurricane alley, and its very heavy.
This van has been a gradual project for 5 years now. Been back and forth to Maine, New Mexico, Colorado, etc usually several times a year. Each year I have made changes based on enhancing comfort and convenience. Total project cost including the van is now a little over nine thousand. Pretty cheap for a comfortable B. The full size bed stays made up at all times. Would like to have a hanging closet, but don't want to make the open space any smaller. 19" flat screen mounts on bookcase when I take it.
