insulate the area that the fridge is in. Keep the heat away from the fridge and you will lower its duty cycle. Just don’t block off the cooling vent. That is not an exhaust vent, it does not have an engine, but it does have a compressor which needs air to cool it off. I would turn the fridge around 180, so the vents where on the inside, just make sure you have a couple inches of space near the vents fins, and there is a path for air to reach it.
This should quiet it down, lower the duty cycle and save battery life.

I looked up Costway. Looks like they are a pretty big/established company. The price on that fridge is definitely right compared to their competitors. Interesting about the battery cut off. Thanks for the info on this fridge.

Excellent information. Thank you very much.

Another thing to consider regarding shut off due to low voltage is resistance in the wires that run to the fridge . Using the cigarette lighter adapter that plugs into the already fairly small automotive wires adds to the resistance . Using a 12 volt extension chord would really add to the problem . Bigger gauge wiring from the battery or direct connection (cut off cigarette lighter adapter and add ringlettes with in line fuse ) is best . I have the CF-18 that we use as a dedicated freezer and had low voltage ( resistance ) shutdown . Direct connection to the battery bank ended that issue . The fridge is designed to be used in an automobile at the beach etc… So to keep from having a dead battery when it’s time to leave , the manufacturer designed the fridge to shutdown before that can happen . I am speaking of the CF – 18 but it probably applies to other cheaper fridges as well . I don’t think they are putting computers in them , but I could be wrong . Hope this helps . Thanks for the video .

That is the exact one I have in the shuttle bus. Bought it in July of 18 and very happy with it. You did get a good deal I paid 490.00 for mine at that time… Happy travels.

I have the same refrigerator….Have had it for about six months now…..Works great … Great price.
All the reviews we from people that just got theirs. so I took a chance and so far so good.

Nice review. Good to know about cheaper alternatives. A quick word on my experience with a 100ah Battle Born lithium. It has a very flat discharge voltage curve. At a mild draw rate of 10 amps/hour, after time, the battery will be just under 13 volts at 80% discharge (80 amps used). At 12.7 volts it is spent and the battery management system will shut it off. Voltage curves can be found on the Battle Born website. I have had no problems running a Dometic 28 CFX in the last year. So far, the lithium battery has been a godsend for my older van, with light weight, compact size and a whole lotta usable power.

Thanks Brian. A couple of thoughts after having changed fridges in my class B RV before. Run at 38 degrees and turn it off at night so you don’t hear the noise. If you turn it off when you go to bed and turn it on in the morning, everything will still be nice and cold and you will not be disturbed. Experience! 🙂

The higher compressor cycles means lower installation of the units walls

Hope you get many years of good service.

Good knowledgeable advise my friend. Quick question on your solar, are your 200 watts enough for your batteries? I always thought it should be 1 watt for 1amphour to be able to recharge to full in one day. Now that you have a constant drain are you finding that you may need more solar. Can’t remember if you have a generator or not, but that would be a simple fix. Just run a gen at the end of the day to top off.

As usual, time will tell. Keep us informed. I really enjoy your candor and honesty.
