Well our cooling unit has failed, pretty sure no cooling on gas or electric. Noticed some dreaded yellow powder and a slight smell of ammonia.So now looking at the JC Refrigeration 12 volt compressor cooling unit. I have the room for it, and it seems like it should work better then the absorption unit.Are there any members that have real world experience with one of there units?Our refer is a Dometic RM2862, the replacement unit runs $785, install is $0.00 as I will do myself.We replaced the cooling unit 8/3/2018, so got just over four years out of a new unit. A new absorption unit runs $740, and a rebuilt is $450. That puts the cost on par with absorption unit.We full Time and mostly park host, so almost always have power, we have two Interstate SRM-27 batteries in parallel, if without power.

“Almost always have power…” can be a fridge cooling and battery disaster if you run out of battery power on those occasions when you are not plugged in. One hundred useable amp hours can go pretty quickly when everything is on battery power.

I am on my second JC conversion (two different rvs) I will never go back to the old way.:C Install is easy if you read and understand the directions.:B Our present refer is a 4 door Dometic and has two compressors. One for the fridge and one for the freezer a much better arrangement for a large fridge. I do have 1000 watts of solar and a 400 AH lithium battery.All in all I say got for it you will never look back!!:B

We don’t boondock, only need to deal with the occasional power outage we have two Interstate SRM 27 deep cycle batteries in parallel, that should run the refer over night and the furnace.

Your SRM 27 deep cycle batteries are NOT true deep cycle batteries but are RV/Marine batteries. They are compromise batteries. On a cold night they would probably NOT run the furnace and the refrigerator all night. The furnace blower is a high amp draw item.

Furnace alone T-stat at 65, outside low 30’s ran all night, on a single five year old SRM 27. Now run two in parallel, I didn’t see an issue. That was for a nine day period, charged during the day.

OP, wondering if you have any updated info on usage? How many Amp Hours do you estimate the unit uses?
