Kind of ambiguous terms. Cold to me is 35 degrees. Cold in ND is -40. Will it be comfortable down to 20? Yea. Above 110? Yea if your in shade and have two AC's running. Both extremes will require a lot of propane and electricity, but are doable. We own a Cedar Creek and winter 2013 we were in the Columbia River gorge with constant 25MPH east winds and a couple of weeks in the teens with snow. We did OK, but it was expensive. Not something I would consider again. Thats why they have wheels, so I can move to where it is warm.
