refrigerator. Gas vs electric.
My trailer stays on a permanent site. The electric is metered at commercial rates in MA. $.24 kwh. I determined that it would be much cheaper to run the fridge on propane vs electric. I've been told the freezer won't get as cold on gas. Anybody have experience in this? WH is on gas. Never thought of the fridge.

We keep our fridge on elec, LP backup for power outages, and freezer kept things very cold.

My question is, "Does the freezer work equally well on gas."?

I just learned something about the Norcold Auto (no adjustable thermostat.)
Ended up throwing away more than $100 in food. The unit auto de-thawed.
It has been -4 to -16F actual temps. The unit shuts down at these temps. 80 degrees inside water runs fine. But like extreme high outside temps, low outside temps affect the units cooling capacity.
Been full time just over a year and in hard cold the unit is made for such.
Just never this long in sub zero. The fix is to block outer venting for the unit and a small heater that comes from outside to the roof vent. Not going to do that in these temps. Yet It will have heat coils VS simply summer extra fans to help vent above 95F

I think mine freezes better on propane. I would however check your math. I feel your monthly rate fore electricity would be cheaper than a couple tanks of propane. On mine I can go two to three weeks on a 20lb tank at $15.

Often times absorbtion refrigerators (including the freezer) work slightly better on gas. The gas flame makes more heat than the electric element to boil the ammonia.

I keep a digital temperature gauge inside the freezer. Runs at around 5 degrees on both elect and gas. No difference.
I think elect is cheaper and use it whenever possible.

X2. Gas may do a quicker cool down but otherwise ours is always on AC (auto) and propane backup.

As stated in my post, the electric is commercial rate in the camp and all camps in MA. $0.24 kWh.  My home rate is residential in Florida and is $.11  kWh. The break-even point is about $0.15 I'm told. At $.11 kWh it would be cheaper to use electric. Florida has one of the cheapest rates in the National Average.

Well, it would be interesting to know how the break even point was calculated. Assuming equivalent efficiency for gas and electric, we would need to know the BTU value of the gas as it is applied to the burner, and the BTU value per KW of the electric element.
Any smart engineer out there with the answers? I am an engineer but not so smart anymore.
Or who did the $0.15 calculation?

My experience mirrors others here. When we prep for a trip, I turn on the fridge on gas. It seems to cool better and faster than electric. I can also hear the fridge “running “ on gas easier by the sound. I always listen for the flame when I first turn the unit on. I have a question: why are electric rates so high up there? Jay

Answer: Taxachusetts and it is commercial rate not residential. The park is a business.

Here you go. Now you'll be a smart engineer. 
Electric or Propane

$.24 kWh ain't cheap.
