It’s good datas, thank you. It’s a Florida’s 4 seasons trailer! There is no rig that will stand cold weather for a long time because there are too many infiltration weak points: water inlet, back of the fridge, back of the water heater, door, windows, maxxair, roof vent , weak insulation factor (R…) etc……but Oliver is way better then other type of construction with a double haul and no slides out……it’s designed in case of a nights or two below freezing but not that much. 4 seasons in Eastern Canada need R60……!
