Here is what I have been looking at (and thinking about) so far…

Harbor Freight Reasonably priced Inverter (s)
Battery Minder, well reviewed battery charger, reasonably priced.
I just received these folks book in the mail yesterday “Living on 12-volts with Ample Power”, It is full of diagrams and has chapters on just about everything. It was about $15.00 plus a couple bucks for shipping off of Amazon, my copy is used and arrived in very usable condition.
Quick but useful overview of RV electrics.
Excellent information here. You probably already have this link to Phred’s poop sheets.
Xantrex Prosine 2.0 2K-Watt Sine Wave Inverter/Charger ... This inverter is a bit on the expensive side (check Ebay about $500.00) but it has an excellent battery charger built in. I am not sure if I am going to spend the money on this one as of yet.
Inverter transfer switch (RV electrics information)
You cannot have multiple inverters connected in anyway, they will be out of phase with each other and cause a short.
I grounded (green wire) the receptacles to the bus, which really doesn't do any good unless you also ground the bus in some way.
Then I ran run the black wire (hot wire) and the white wire (neutral or common wire) to the switches and outlets that a want that inverter to power. You must keep each of these circuits separate between inverters. You will need to decide what you want each inverter to power and only hook up that one inverter.
Not sure what you are trying to do but I should point out that if you want to use multiple source (although you can only use one at a time as I pointed out) a transfer switch can be put inline to move your circuits between sources.
Lets take for example you have a circuit that runs all of your kitchen area appliances and it is plugged into a transfer switch. One side your 1000W inverter is plugged into it. On the other side you have plugged in one of your 750W inverters.
Lets say you want to use this single inverter to power everything and only turn on the other two smaller inverters when you need the extra power. So you can have this 1000W inverter powering everything and if you know you are going to need some extra power when you use your microwave you can turn on that other 750W inverter. When you do this the transfer switch will see that you are now supplying power on the side and it transfer your kitchen circuit over to running off the 750W inverter, leaving the 1000W inverter to power everything else in the bus except this circuit. Then when you turn the 750W inverter back off it automatically transfers over to the 1000W inverter again.
This is how most RVs switch between generator, inverter, and shore power. Transfer switches are very handy and if you use them in the right places they can be very power tool. Also you can buy inverters with built in transfer switches, the one I have in my bus is one of these.
Here are some examples of just transfer switches:

Here's a cool thing about watts. Since they are volts*amps a watt is a watt is a watt. It doesn't matter which side of the inverter you are talking about because the unit itself takes into account both voltage and amperage. So...your 183.6 watts on the AC side of the inverter is 183.6 watts on the DC side. The conversion comes in figuring out amps. 183.6/12=15.3 amps@12 Vdc. So were does that multiplicative factor of 10 come in? When going from amps@120Vac to amps@12Vdc.
Ok...enough of that garbage. I have a small fridge similar to the one you're describing. Mine is actually a little smaller, but has a slightly higher electrical draw (it's OLD....like R-12 old). It works great in the bus. The electrical draw really is minimal considering it doesn't cycle all that often. It is amazingly simple, can be used in the garage other times of the year, and is cheap. I think it's a good solution for anyone that isn't going to be doing a lot of boondocking without solar or other means of charging the batteries back up. I have mine mounted under a shelf for the TV so it is out of the sun which probably helps with efficiency, but more than anything I did it for space.
One word of caution. Size your inverter for at least 3 times the rated load IMO. Mine surge to 1500 watts, but with other stuff running the voltage drop can be enough to make my PS2 cycle off. Some of that might be my wiring, but I wouldn't go smaller than the 750 watt inverter I have on the fridge along with just a few other things (I have two inverters and try to load the fridge on one independently as much as possible).
