For refrigeration, you might wish to consider the Vitrifrigo 12/24V DC and 120V AC unit.
The Danfoss high-efficiency compressor works at fairly low power drain on either 12 or 24 Volts and automatically selects the mode.
For 120V AC operation, the fridge includes a 120V AC to 24V DC power supply which will be used whenever AC power is available (Genset or shore power).
I had almost new one on my boat (Carver 355 Aft Cabin) which was totaled in Feb 2011 in an ice storm. Brought the fridge home and currently use it in the garage for pizza and beer!
It will go into "The Money Pit" if the 3-way box that came with the coach decides to not work properly.
Bought from Defender Marine supply.

OK.. this is what I have installed so far:
1) 3, 120 watt photovoltaic panels mounted flat on the roof
2) 1, 1500 watt inverter/charger connected to the PV panels as well as to a 15 amp shore power connection
3) 2, 100 amp hour lithium batteries
4) 1, Dometic 12v portable refrigerator/freezer that sits between the driver and passage seat and doubles as a sort of table top and drinks receptacle.
5) 1, microwave, rated at 800 watts (plus any surge)
6) ALL the lights are LEDs (lots of them)
7) Several 12 volt cigarette lighter type outlets
8) created a space for a 4.1 cubic ft under counter frig (now occupied by a $50 home depot special)
9) installed a CAT vented propane heater (has a 12v fan for the exhaust system)
I have removed the inoperable Onan as well as the rooftop AC. Also installed a completely separate 110v system for the temp. frig and to run power tools etc while working on the coach.
Now... gather enough cash (about 1K) to buy the 12v frig.
We are in western Canada so AC although nice is not necessary (well that statement is still open for debate) So I'm looking at a AC system that can work while driving.... still looking, any ideas?
This last summer all worked very well, a couple of trips to the national parks in the rockies (not hot enough for AC) and the PV panels have kept the batteries over 13v all the time.
We calculated and then attempted to balance the PV input with the expected electrical demand.
