The exact same fridge from truck fridge is $300 less than isotherm from marine suppliers. Both are built by the same people. Look at them. They use the same model size name. Have the same shelfs, same compressor. Also note the door can be made to open left or right and the front panel can be switched as I did with wood veneer or an aluminum sheet.

Thoughts on 12VDC Refrigerators

JRF0st3r, here's a few thoughts on your quest for a candidate 12VDC refrigerator. I'm new to the forum but have a long history with RVs since 1983.

12VDC refrigerators for RV use may be 110VAC/12VDC powered. The refrigerators will run on 110 if it is available and switch to 12 VDC automatically if the 110 goes away. A few are designed to run on 12VDC only.

I have a Norcold DE490 still in service at 19 years. It will run for 48+ hours on one 12VDC 115 A-H battery. The Norcold model that replaced the DE490 is the DE-0788. It has a 0.5 cu. Ft. freezer and a 3.1 cu ft. refrigerator section. The refer uses 0.8 amps @ 110VAC and 3 amps @ 12VDC. Estimated power consumption is 36 A-H per day. Weight is 62 lbs.

A larger Norcold is the DE0061 and EV0061. It has 1.7 cu ft. freezer and 5.3 cu ft. refrigerator section. Power consumption is 0.4 amps @ 110VAC and 3.2 amps @ 12VDC. Estimated daily power needed is 36 A-H. Weight is 105 lbs.

Dometic has a model CR1140E with 4.81 cu ft. It runs only on 12VDC and draws 5.9 amps. Estimated power consumption is 72 A-H per day.

A world famous DC refrigerator manufacturer is SunFrost.A good model for RVs is the SF RF12.This unit offers a freezer with 2.05 cu ft. and a refrigerator section of 8.07 cu ft.Daily power consumption is 24 A-H @12VDC @ 70o and 39 A-H@12VDC@90o.The unit weighs 230 lbs. SunFrost lists a price of $2579 + a $50 crating charge.

To summarize, 12 VDC refrigerators can be continually powered by an adequately sized battery bank supported by a PVC system that can generate a daily A-H harvest equal to the refer’s daily power consumption.With extra battery recharge sources from shore power, genset power, or alternator power from the motor coach’s engine or tow vehicle (TV) engine, there should be no shortage of power to keep the refrigerator running.Other advantages found with the 12VDC refrigerator include: no requirement to level the RV for safe refer operation, no need to buy propane for the refer, no additional load placed on an existing inverter (or possibly eliminate the need to install an inverter or replace an existing inverter with a larger inverter), and possible longer life compared to a propane RV refer.

Look for "Koolatron" plug in coolers. I have four of them, one in each car, and the others as req'd. They drop the inside temp about 40Deg. below ambient. One of them fits between the seats of a van, or in the back floor of our Camry. No Ice Cubes needed, just keep it plugged into a 12VDC outlet and the food stays Kool.
