Hey ya'll, We're not wanting to pack the camper up for winter, I'm trying to figure out how long we can go comfortably. We have an Aliner Scout so NO propane heater, we use a small electric radiator style heater and last week it got us from mid 40's up to 70. If it goes below 32 degrees will we have plumbing freezing issues? All it has is a city intake and a sink drain. Does anyone have tips or a heater that works in more extreme temps? I have a baby as well so I cannot just "bundle up", I would need to actually get the ambient temp high enough so everyone is warm enough. ETA- our heater was pretty much maxed out by the mid 40's so if it gets colder I'll need to find another that works better. Also worth note, with two kids safety considerations are paramount with heaters ...open flame type would not work for us .
