I did some research and yes, it can approach zero degrees. But the way you worded it it may be mistaken for "below zero." That's way too cold to be in an RV.

5-10 degrees will not be pleasant. Like your a/c trying to keep you cool when it's really hot, your heater will likely be running 24/7, and you will need LOTS of propane.
