IMHO there is no such thing as a 4-season camper, ie. one that can be used in the dead of winter. It's not a house.
One option might be to buy a 3-season camper and rent a cabin for the really cold times and locations.
Dick, the weather is different here in the winter than in IL. Way warmer in the areas that the OP is talking about.
All the coastal areas are rarely below freezing in the winter. Weather hovers in the 40s most of the time. And the Cascades at the ski areas are only just enough colder typically to turn the rain into snow.
In all my winter mountain outings in the Cascades in the last 8 years, we ski and snowmobile, I can think of 2 "cold" days, like zero or single digits in the morning and far more days where the snow turned to rain or vice versa during the day. RVing at the ski hills or snowparks is fairly common and popular out here due to the generally mild temperatures.
