I have pulled the original frig and discarded it. It was 12V and 110V ac and worked ok but the liner was cracked and the shelves rusty.
Planning on using only 12V dc and installing solar cells on the roof.
Also LED lighting and house batteries that will keep all the systems in balance.
Any ideas or suggestions?

I went with a Norcold 3-way for the more (electrically) efficient, LP use while dry camping. Norcold does make a nice looking AC/DC model. I don't have any first hand experience with this unit, but it specs out nicely:

Our recommendation on refrigerators is the one with LPG along with the
electrical if your not going to be plugged in or running the
generator.
The battery drain is more than you can recover with an average solar panels.

Personally I don't understand using an electric refer if one wants to dry camp for several days in a row. <snip>
Bottom line,
get the kind of refer that suits you. We can offer advice but it is only good if it suits your particular need.

Dan,
Since the majority of my investments were taken from me and the dream of a comfortable retirement can now never happen, the decision for us was simple. A reefer we could actually afford or figure out how to use ice. Whatever RV unit you purchase, you can expect it to cost an approximately equal to - A full set tires, three thousand miles of fuel or the full cost of at least two GMCMI rallies. By cutting that to less then a third, there were some things that could still be enjoyed.
Everything is a compromise.

I really hate that for you two Matt. We all do what we have to to make things work for us. One reason I like the GMC, can make it just the way I like it. Never liked stock vehicles so our's has nothing original left in it, maybe the windshields. Every time I think I have cash for them something goes. I used windshield money to buy the new Norcold when it died out in Oregon. Keep coming to the conventions. As we all know you have a lot to contribute.

I didn't mean to get anyone's back up, I just read how he wanted a replacement all electric fridge.
We don't dry-camp as a rule, unless its in camp Walmart for a few hours of sleep.
We have a single 100Amp/hr SLA battery that is about 6 years old. From experience I know that it won't start the compressor after about 18hrs of running on the battery. Some quick calculations show that would have consumed about 75Amp/hrs from the battery, which is way more than the battery should have been discharged.
When this fridge is running, the Inverter shows its taking about 80 watts of power (not sure if that's input or output power) so lets assume 100 watts. It runs for less than 30mins per hour so lets say 30 minutes per hour, so that's 50watt/hrs X 24hrs = 1200 watt/hrs per day. Starting current is likely 500-600 watts for several seconds.
I don't have any experience with solar cells on an RV, so I don't know how much real life power you get from a (say) 200w solar cell on an average day, but lets say an average of 50% of that for 12 hrs of daylight (summer daylight is more than 12hrs, but I am being conservative). So that would be 100 watts x 12 hrs = 1200 watt/hrs.
So with some conservative figures, it would seem that a 200watt solar cell should keep up with this fridge. So adding in some additional fudge factors you would want to at least double that to have power for LED lighting, TV etc, rainy days etc.
So it seems like it can be done, but the additional solar power required does add alot of cost too!
Maybe one of the Electrical Engineers can correct my calculations and assumptions.

Bruce--there is nor right or wrong to this one. Much of it boils down to how we use our coaches, what our priorities are and what we want or can spend. When my 3 way Dometic crapped out I went to 2 electric refigerators (one can also be set as a freezer) I boon dock almost exclusively, although usually 3 to 7 days at a time. Between 4 good batteries, a solar panel, and my Kipor, I get along just fine. If I boondocked for months at a time, I may change my mind. If my Dometic was still running, I'd be just fine with that as well.

Temporary tilt angle shifts while driving don't count. The constant
movement keeps the refrigerant moving around.

Generally, if it's more than half a bubble on an older gas fridge, or a
little more than half on the newer ones, turn the fridge off. IIRC, even
an hour at the extreme tilt is enough to start the deterioration of the
fridge.. A night without the fridge running won't hurt anything but the
ice cream in the freezer.
the mfgs claim for the really new ones is, "If you're confortable at the
slope, it's OK", but I think I'm OK at a lot more tilt than the fridge
is. We use just a skosh more than half a bubble as our criteria.
