Do the "dollar bill test" of both refrigerator and freezer gaskets. Should be reasonable resistance to pulling out the bill all the way around.

Verify that the refrigerator condensate drain either has a drip loop in it or a restrictor in the end. If neither, warm outside air will rise into the refrigerator.

No icemaker (except for Frau Blücher) it collects about a 1/2" of snowy ice on the back wall of the freezer an the aluminum fins inside the fridge,,

We generally had to defrost every few months during full time use.

How LONG does it take to ice up? Are you talking Freezer or BOTH? Doug

You might shut off the ice maker and switch to a small countertop ice maker, More ice, faster, and no release of moisture into the freezer.

Your "Frost Free' unit at home actually has a HEATER to melt the ice
But the RV Absorption unit does not.

I found when my Ice Maker failed...... The unit did not ice up nearly as much after I removed it and went to a counter top.
