I'm using a GE 9.8 cu.ft 12V fridge. Very similar to the Everchill. Replaced my POS Nevercold with it. I have 4 GC 6V batteries and 400W of solar. I can go for days without worrying. I'll never go back to absorption.
Back story is that my 1.5 year old Norcold had clogged lines. I tried everything to remedy the situation except take it out and burp it. It started to not cool after the 1st year. everything was fine as far as the heating element on gas or elect. I did the by pass fix and the temps never wavier'd much from the outside ambient temps. I even installed two fans on the roof cover to help draw air up pass the lines.
I could've went with a JC refrigeration convert kit but decided to not have to deal with the Norcold electronics that also seem to be an issue from time to time.
started researching and it seems that 12V fridges have been in the marine world for years. I found my GE at a local appliance store. $950 with a 3 year warranty. about the same price for the JC conversion. But I got 2 more cu.ft, don't have to deal with propane or the whole elec to propane back and forth situation. The GE cools down in a few hrs and holds 35-36 and -4 to 10 on the freezer. It's quiet and I can run it while traveling without worries.
My 12V fridge is 9.8 cu.ft and fit right in the hole for the 8 (7.5) cu.ft Nevercold.
I wired it directly to a 12V breaker on my converter box.
Used some of the NC trims to finish it off.
Inside is like a res fridge. More open and usable. If this one fails I'll get another 12V.
I will say though you do need good batteries and at least some solar. 200W would be sufficient for several days of nice weather and not using the house batteries for big items. Solar's free and panels aren't much if you shop around. Mine were only $95 or so each. Pick up a simple solar charger and thats all.
The extra room and simplicity alone are worth it to me. I would never do a res fridge as they require an inverter and draw too much power.
