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 think that's because those have an electric supplemental unit to augment when temps get too low, something RV units don't have because of electrical limitations.
