Cold weather camping.
My wife and I just completed a last minute tour through the Rocky Mountains in Alberta. We left Fort Saskatchewan and stayed Saturday, Sunday and Monday in Jasper. Travelled down the Columbia Icefields Parkway and stayed in Banff until Thursday. Had a great time even though the Campgrounds are full. Last couple of nights were cool -3 Celsius. Trailer was warm and comfy. What's the coldest any one has stayed in their RV. Our 2015 210uds seemed to perform well. No issues even when we woke up with snow on the ground.
