We bought 2, in 2014. 82 qt and a 50 at. 1 or the other, sometimes both have been running since. When not camping, they get used as overflow fridge/freezer. We absolutely love them. When we bought ours, afaik the ARB's were the only ones that would operate at up to a 30° incline and have a Danfoss compressor. Shortly thereafter, it seemed like there were dozens more every year.
The price hurts, that's for sure. But not having to hunt for ice is priceless. The very first time we took the 50 qt ARB fridge camping, the power went out for 36 hrs. I plugged the fridge into the aux battery. When that started getting low, I recharged it with Honda eu2000i. Everything worked great.
We always take it when shopping far from home, to a distant market or farmers market. Once you get one, you'll wonder why you didn't get one sooner. It's life changing.
