Refrigerator - Gas or Electric Cools Better?

Has anyone done testing or has seen a reliable test report concerning whether the Dometic RV refrigerator cools better when on LP gas or on 120 volt electric power? Most of the time mine cools very well on either heat source, but a few times when it was over 95 degrees with the refrigerator side in the sun it got above 50 in the main compartment. In such a case I'd switch to whichever cools better. I plan to add fans both in the interior coils and on the exterior coils to help, but using the best heat source would help, too.

I have not tested my new Flagstaff with domestic fridge, however my winnie with a amish cooling unit and two fans in the chimney got colder on propane.

IIRC the LP puts out more BTU's than the electric, meaning it will cool better. The key is to get the hot air out of the compartment and keep air moving across the coils.

Where did you get the information that the gas burner has more BTU'S than the electric heater? I haven't seen it.

Propane does a better job than electric.

Read it on the internet so it has to be true!

I have seen it in the fridge specs, I will see if I can find the exact numbers, it varies a bit from brand to brand and by the size of the fridge. It is not a massive difference, but the gas does put more heat into the system than the electric if everything is equal.

As I stated before, getting air moving is the number one thing, keeping the incoming air as cool as possible is the second, park the fridge side of the RV in the shade on a hot day, if at all possible. Circulating air around in the fridge section doesn't hurt either.

Read somewhere (probably this forum) that adding a sunshade on the outside wall where the fridge is will improve cooling. Just need to make sure there is a space between wall and shade so air can circulate.

Yes. I typically use the Valterra one on the outside in the fridge compartment and a computer hard drive cooling fan attached to the fins inside.

Stay away from the Camco Solar Refrigerator vent, they don't last long and when they break the allow water into the fridge area.
