One year long term update:
I've had the Edgestar 43 qt model for a full year now and it had been great. I did cut off the supplied 12 volt cigarette lighter plug after the 1st day of testing and replaced it with an anderson power pole connector, with the new connector I have never lost power.
I have had one issue where I had to pop the cover off the elecrical panel and plug some of the connections in a little tighter (SUPER common know issue with these fridges). I did email edgestar tech support and they offered to take the whole fridge back if I was not happy. They also sent me out a complete computer/brain/control module just in case that was the issue, no charge and fast (it is still in the box as it was really just an intermittent/loose connection).
It is currently loaded with beer conducting a test of my new 80 watt solar panel. The panel appears to be able to keep the fridge and the battery happy - it has been going for 3 days now with ZERO net battery loss.
I have used it in my camper A LOT and it works great - it keeps a very steady temp and set at 37 degrees it impresses people with ice cold beer. I have also strapped it down in the back of my truck for some light offroading with some dust and rain and it worked great and showed no signs of wear from bumping around for 8 hours. It has also survived a few college football tailgaters with near constant openning and closing and even some lid slamming...
I would buy another one for sure. I'll update this again next year.
