You have solar. That is really the key to extended off-grid operation of a DC compressor marine fridge.

Look at Isotherm and Vitrifrigo. Both made in Italy. Excellent quality at comparable pricing to RV fridges. These are my go to brands, depending on the size that I need.

I suspect that your propane burner is not putting out enough heat so your cooling is not as good as it should be on propane.

Possible causes are:

Dirty burner caused by rust falling down from the boiler tube and partly closing the burner screen or outlet. It may need cleaning. Very common problem.

Burner mis located and not in center of boiler tube (rare but can happen)

Low pressure on LP gas lines, causing insufficient burner heat. Common issue, needs propane regulator adjustment to 11" water column or regulator replacement.

Partly clogged gas burner orifice causing low flame. Not common, but happens. Needs cleaning with alcohol and compressed air.

Spiders or other insects somewhere in the burner tube. Needs cleaning.

In general the propane burner create more heat than the electric element so is faster to cool down. Yours may not be up to snuff due to one of the above issues. The fact that it also wants to go out and not relight may also indicate one or more of the above issues is present, although I am not discounting the need for an air baffle to keep the burner lighting when traveling. I had one which was a new unit but the old air inlet simply caused the flame to blow out/not light.

Thanks for all the suggestions. We'll check them out!
