We're definitely over the dark side.
We removed our old 3 way and replaced with a GE dorm type 120v only fridge
. Lots more fridge space and it really works! PLUS it cost about $100 from Sam's Club compared to a much smaller replacement Dometic unit at over $1000 ... yikes.
On the road, we run it from a group 27 deep cycle battery
via a cheap Vector 1500 watt inverter. The camper battery
is charged from the tug system. The inverter is overkill but we found that a 400 watt inverter wouldn't start the fridge compressor and I had the 1500 on a shelf in the garage. When we stop for the night I check the battery
voltage and I've never found it to be undercharged. Usually it reads 12.85 or so.
Also the 1500 watt inverter would likely run the microwave
for at least 5 minutes before it kills the battery ...
Look Ma ... no gas!
