Stayed at Roosevelt lodge in YS in early June. Tiny 2 bed log cabins. No insulation. Had one of those tiny wood burning stoves. Had to get up every hour during the night to feed it. It was 32deg one morning when we got up.
Also, if you dont run your furnace, it will not heat your underbelly. Frozen pipes.
You will need to skirt. If you are boondocking, you will have to fill your freshwater tank and use your pump. You will need to use your tank heaters to keep from freezing up.
Look in the Forum under "Brrrr, it's cold outside. Winter camping". for lots of good info.
