I have been watching and researching fridges for a while. I can not justify the cost of one yet, but they do seem to be stable in price while updated features are added. There are a lot of manufacturers offering many options. I like the newer fridge AND freezer models that offer the best of both worlds. I keep coming back to the SNOWMASTER brand for its price point and dual system in their expedition series. ARB always seems to be at the upper price-point in everything they offer. Great customer service, but sometimes the quality is not always there.
ARB should have offered their new ELEMENTS fridge as a dual zone-fridge and freezer. That seems to be the industry direction, and reflects customer preference trends. I am surprised they didn't offer a thermal cover for this model, even though it is a all weather desighn. By the comments above it does seem to be well insulated and energy efficient. Being in the desert southwest, high efficiency and low power consumption play a big part in summer when temperatures of 105-115 degrees outside everyday are the norm.
