If you were heating with electric heat pumps, that could be the problem. Heat pumps only work till about 40 degrees. Then they just blow cold air. Nothing wrong with them, that is how they work by design.
Always keep propane when it's cold out.

I work for an HVAC manufacturer, we design heat pumps to operate down to minus 20f.
I suspect those are bit more advanced than the $600-$1000 units that are popped on the top of most RVs :)
As an aside, in good conditions I've been able to squeeze heat out of my RV heat pump down to 30 but that is about it...
