I bought this model in 2012, and it has been a trusted camping partner on many off-road excursions and also on many boat trips. A couple of months ago it stopped working on 12V, only on 110 it would cool. I opened it up and tried to investigate the 2 circuit boards, but I found no smoking gun.The Danfoss Kompressor is a solid unit and still works on 110V. The unit is well constructed in general, but I am disappointed that it stopped working after 10 years. A friend of mine retired a working Engel unit after 17 years because he wanted a dual zone. So there is annectotal evidence that other units outlast ARB. The temperature distribution is not ideal due to the one sided cooling plate, but it is not a big deal to me. The removable hinge is not removable anymore, it requires brute force (even after lubrication). Probably the rattling on countless hours of washboard in Death Valley wore that feature out.I had bought the cover together with the fridge, but in hindsight I am unsure if it was worth it. It has a pocket that held my power cords and the manuals, which is a nice feature to keep everything together, but after a few years the metal clips stopped holding it in place and the glue on the velcro tape let go. I also read some performance test that it does not help significantly in keeping it cooler. I am now looking at a replacement, and I am undecided on the brand. In the end it lasted 10 years and it never failed on any if my trips, and I have found the form factor useful. For example the unit is only 17 in high, but in my truck the height became a problem due to opening the lid, especially after it could not he removed any longer. Many competitors boxes are even taller. The display on top and the power hook ups in the back are ideal in a fully packed truck. Power cords in the front are always a hassle for me, and a display on the bottom is not easy to read in my set up. ICECO makes a few good looking units with a Danfoss compressor which I really like. I used to be a fan of the metal housing fridges like the Engel or ICECO, but the old Engel from said friend started rusting in a few spots. More cosmetic than anything, but my ARB housing is plastic and even though it is pretty worn as well (even through the cover was always on it), it never rusted. That is especially important since I use it also on my boat around saltwater. ARB is pretty expensive now, National Luna with the stainless housing are similarly priced., as are Engel. ICECO is less expensive snd uses Danfoss components, and has a 5 yr warranty on the compressor. The form factor and placement of the interface is a bit of an issue there, but it is significantly less expensive.
