I spent way too much money keeping my NoCold 1200 going because of the myth spread on this forum that you cannot boondock with a residential refrigerator. In the summer we usually boondock 5 days/week.
If your rig has one battery...residential is not for you.
If your rig has two batteries...doubt residential is for you.
If your rig has four house batteries...residential is a viable option by adding two more batteries as you probably already use a fair amount of power and you probably have an inverter and so way of charging your batteries.
Two batteries will run my 21 cuft refer for 30 hours before needing to be recharged. It draws 8 amps DC (96 watts) measured before the inverter and the duty cycle is 40%. That's 75 AH/day. No need to shut it off at night BUT I do turn the icemaker off until I crank up the generator for the hour at dinner and half hour in the morning when making coffee...actually less than before going residential as I add another 100 amp charger and I'm up to 500W of solar.
