I too am satisfied with my Nova Kool. I find some (5-10 degree) fluctuations in temps, however, I attribute that mostly to imprecise thermostat or our use patterns.

I had to add more ventilation through the installation of a fan since the compartment was not adequately ventilated by Airstream. I haven't yet traveled in hot weather, but on my driveway the compartment could reach 120 degrees on hot days or when that side is in the sun. In addition to the fan, I added insulation which cut temperatures by 10 degrees. Now, when the temperature behind the fridge reaches 100 degrees, the fan comes on and stays on until it cools back down to 85. Will still try and avoid hot weather trips, but I'm hoping that what I've done helps.

Hi, I had a 12vdc Nova Kool 6800 two door model for a while and as stated above, it cooled fast and was trouble free running on batteries. It did not matter what the cabin level was, it worked.

Just this morning I placed an order for a 12vdc one door 4.2 cf Vitrifrigo refrigerator only, no freezer. Freezer is separate. It's going in our van. Will be happy to report back.

For those looking to replace older non working units, Vitrifrigo has an extensive line with no rear condenser looping coils. A wide variety of sizes to choose from. They use a small heat exchanger with fan blowing past core and compressor. I chose a model with external heat exchanger that will be housed under bed in storage area. This allows me to fully insulate the box without dealing with rear coils or heat exchanger behind box.

Hi David,

I purchased the Vitrifrigo C130 without the built-in freezer and stainless flush mounted door, both options $. I did not want AC option but it comes that way. Bought from Sure Marine in Seattle for $950 + like $140 shipping to Orange County CA.

Aside from the size, I chose this unit for its use of a separate, remote, compressor/heat exchanger combo attached to fridge with its insulated freon umbilical line. The external compressor/heat exchanger combo can be placed away from fridge but not by much. Normally it's embedded in the rear which eats fridge capacity. With the detached combo the fridges' outer walls are clean and can be stuffed into a cabinet with no need for air gaps and in some cases surrounded by additional external insulation. You can not do this with a rear mounted compressor/heat exchanger as it requires air flow. My compressor/heat exchanger will be accessible and have airflow to and from cabin.

The unit will not be installed for a couple of months as I have many other projects demanding my time. I have run the unit on AC, soon DC when finished building the battery bank on the test bench. The external compressor/heat exchanger combo is very quiet, almost undetectable. To run at 40F internal (as a refrigerator only) I had to set dial to 1, 8 being highest. Unit was empty. Remember no freezer. The door handle is marine latch type and very solid. Without the built in freezer refrigerator capacity is 4.2 cubic feet.

Per Virtrifrigo cutout dimensions is as follow::

560mm, 22.1" Depth
540mm, 21.3" Width
768mm, 30.3" Height

See their link: C130L (external cooling unit) - Camper/Caravan - Vitrifrigo

For some reason my stainless flush door has an indented commercial type latch different from the one shown on link above.

Good luck,

Santiago

This thread is a bit old, but is right down the alley for my question. Like the original poster, I've got a Roadtrek - in my case a 2004 Chevy 190P. I am trying to find a compressor 12V replacement for my existing Dometic RM2353. Rough opening approx. 29 3/4H x 20 1/2W x 21 1/2D. The one unit that appears to be a good fit is the Nova Kool RM4500, but that unit has been around for a while. Any suggestions? Thanks, Steve

I've got a 2007 Roadtrek Agile SS - in my case, I swap out my existing Dometic 3-way with an isotherm freeline 115 elegance, I like the freezer size, Dimensions (LxHxD) 525x794x495mm
It is AC/DC compressor electric-refrigerator-freezer. The Vitrifrigo C130 is couple hundred dollars cheaper, but 1/2 inches too wide for my space!

Thanks for that. Are you happy with the fridge?
It is hard to tell if the 115 will fit in my existing space. The Isotherm specs aren't really clear what the rough opening should be, nor am I clear on what rough opening I have now. Not in a hurry to remove the fridge to measure. I'll keep searching for this info. Steve
