We bought a former rental class C in 2008. Our first trip was early in the spring when we headed south toward Jasper. Of course it snowed and got cold so we could learn by experience. Highway 40 got tough due to quite a bit of snow so we stopped at a rest stop/campsite high in the foothills for the night.
We enjoyed our nice warm camper, really comfortable compared to popup tent trailers. I remember it was -10 C, 15F and the plastic drain tap on the freshwater tank froze up so I couldn’t turn it. I put a warm mitt over it and the tap turned easily in the morning. No other signs of freezing.
It was lucky that happened so we learned that we were okay down to -10. I carried a jug of RV antifreeze on trips that might be colder.
