I have a 12V GE fridge. Going on it's 2nd season. Runs great. It does suck power more then the newer brands but with my 400W solar and 4 GC 6V batteries I have zero issues with battery draining. We are currently on a short 6 day trip. I've been on 120V hookup and dry camped on this trip. My fridge has been on 12V only the whole trip. The lowest the batteries got down to was 12.16V. We ran the furnace a bit and used our elec blankets with the inverter since it got down to 32* that night.
On the open road with a solar panel and 2 batteries you should have zero trouble when traveling.
We had an 8 cuft Norcold before and when it died I got the 9.8 cuft GE for $950 and that price included a 3 year extended warranty. Hard to beat that today.
I wired it directly to the battery with an inline fuse.
I would do it again in a heartbeat. 2 more cuft of space is really nice.
It fit exactly in the space for the Norcold.
I'm pretty handy for me it was a really easy install.
FWIW I'd recommend 2 batteries for daily travel if you're hooked to 120V for the night. If dry camping then 4 batteries and 400W of solar.
