"If you're using good common sense (and leveling your rig): it just seems like a product [ARP Fridge Defender] that is looking for a need..."
Well, have you ever driven your rig up or down an incline in excess of 3degs? Or have you ever been unable to "level your rig" in a boon-dock site? Maybe you live in a idyllic world where you always know your deck-angle, even though a lot of folks don't have a readout, either while driving or parked.
The issue with the
ammonia absorption vapor cycle refrigeration system is that if it does over heat, it can do damage to the plumbing that may result in a fire
at a later date. Each time the boiler overheats, the damage accumulates and, eventually, you’ll have a dead refrigerator.
The Fridge Defend continuously monitors the boiler temperature and automatically shuts down the boiler if temperatures begin to climb out of normal range. Best of all, the Fridge Defend by ARP continues to monitor and
re-starts the fridge once it cools down again, so that your food doesn't spoil. And all without any effort by you!
The ARP also has a feature that
engages an external fan circuit as the temperature of the coil begins to rise, thus serving to shorten the start-up cooling cycle and keep the frig-efficiency at its best, with the least use of either battery power or gas. (if not on shore-power); see my attached picture.
"A product that is looking for a need..." would hardly have a customer rating of "Safety 98%", "Reliability 96%", "Efficiency 78%". This customer stated "I installed an ARP with fan control in my Class A MH. I just love how the Fan Control has improved the cooling in my Norcold."

"Good common sense (and leveling your rig)..." is definitely important, but for the peace of mind I have that my rig will not go up in flames caused by an overheated frig, plus increased efficiency of the automatic fan system, it is worth every dime of its about $200 cost.
