Great idea on the microwave, I was thinking along a similar line, and I have a spot that will work like that.
The unit is a "Progressive Dynamics" power converter 324L
25 amp output, 5 amp charge
3 breakers, 15 and a joined 30/20.
Model # stamped on the tag is 722Q08RMT
Fuse panel is next to the converter panel, and the charger panel is above that.
Currently, I can only find one 110 outlet.
I believe the refrig is a 2-way, and the hot-water tank appears to be gas only.
I will try to get a pic up later, putting away the tools from the tiedown install now.
Raining buckets around here.
