TL;DR - After switching over to a Dometic Fridge, things have been working "just fine." I think I still technically preferred the ARB overall, but the Dometic has a few nice features the ARB did not. And, most importantly, it's actually cooling.So far, the Dometic is working out.
TL;DR - I'm not happy at all that the ARB fridge wouldn't cool on my last trip. I'm going to be reaching out to ARB support to (hopefully) get the issue resolved.My $1000 ARB fridge, now a glorified ice chest.
