We do alot of early spring late fall camping with our popup. As it has heated mattresses, we stay nice and cozy even when we once had an issue with the furnace not coming one - and it got down into the 30s that night (suspect an issue with the propane as had just switched tanks and did not have a good gas flow, which seemed to work itself out when it warmed up that morning.) I now do bring an electric room heater to supplement and save propane.
