That is debatable ! You could be in big trouble if you run out of propane and there is no refill station nearby.
With adequate solar and batteries a 12V compressor refrigerator is far superior to any propane evaporative refrigerator, especially when the outside temps are in the 80s or above.
I certainly would have a generator, even a 2000W portable. Also a DC-DC charger.
I think you'd really have to be asleep at the wheel if you run out of propane. With 2-7.5 gallon tanks, I've gone 30 days with no fill ups and using the water heater too. No furnace for that thirty days though. I'd be thinking in a thirty day period one should be able to come across some propane to fill the tanks.

I got a great deal on a used RV. Sadly there was an issue. It came with a 7 cuft compressor refrigerator that chewed way too much power to be useable. If you want to learn the details, here is an example of the issues:
https://www.exploroz.com/members/145028.75/1/2009/queensland_adventures_winter_2008.aspx?p=%2fblogs%2fdefault.aspx
I could not easily convert to propane because there was no back access and no roof vent. Instead I got a much smaller (4 cuft) Nova Kool compressor refrigerator. It pulls 2.3 amps. The duty cycle time is HIGHLY dependent on ambient temperatures. Around 60 degrees it runs maybe 1/4 of the time. By 70 degrees, the duty cycle increases to between 1/3 and 1/2. At 80 degrees it runs full time. Beyond that it struggles to maintain frozen food and a 40 degree refrigerator temp. I super insulated the compartment, increased the ventilation and even use a couple of computer fans on the coils in hot weather.

Starting with only two 100a/h batteries (assuming wet cells), only gives you 100a/h usable for all your needs…Solar might augment, but with only two 64w panels, even the best harvest might only result in about 6.5 amps, then add to that the refer door seemed to be opening occasionally (ugg!!), and I think you were hitting the ‘sweet spot’ for failure… In this case I would have definitely gone with LPG, and I believe your trusty vendors were chock full of optimistic advice…This is why (per my previous…) having a substantial battery and solar set-up is critical, particularly the battery - this is why I said 400a/h Lithium, due to Li’s deeper depth of discharge, and the vagaries of solar to carry you over to the ‘next productive’ harvest cycle…And with a decent amount of solar, a few amps of harvest is often possible even with full cloud cover…While on the Oregon coast (with 660w solar) I was recently able to get about 6-7amps with full cloud cover and even a small amount of drizzle, admittedly not a whole lot but still enough over a time to ‘increase’ my 400a/h Lithium by a welcome 8% SOC…
I have a pal that has a 9 cu/ft (Danfoss comp) double door refer that runs fine with only two 100a/hr of Lithium and 400w MPPT solar (recently upgraded to 800w - fine for Nevada), and know of another fella that has a 7 cu/ft compressor refer (don’t recall the make), 460a/hr lithium and 400w of solar with no issues…So to achieve true LPG liberty, expect the devil is in the details ($$)…

For the 4.5cf model it draws up to 72 watts when the compressor runs,very manageable with enough solar...
This unit draws 5-6amps when the compressor runs. A 100amp battery will run it, but the charge back from a 100w panel might not be sufficient to maintain the battery. It will depend on how often the compressor needs to run and how much charge back is achieved during the day.

How Many Amps and Watts Does The Everchill RV Refrigerator Use
Question:
Does this use 11A to run the unit or 3A? Does this unit not have an on/offinch switch. Another answer says it must be added separately?
asked by: Joe
Expert Reply:
I believe you are referring to the Everchill RV Refrigerator w/ Freezer part # 324-000119 which runs off of 12V at 2.5 amps. Since watts is amps multiplied by volts, the wattage is 30 watts. This could be easily powered with a 2,000-Watt Portable RV Inverter Generator part # 333-0001.
The Everchill Refrigerator does not have an on/off switch but can be easily wired to a toggle switch like part # PK34571.
