I cant recommend a park but I can do better than that and tell you to forget it. I was in Arvada in November and burned 30 lb of propane a day at times and ran an electric heater too. I also boxed in the area under my tanks and put a heater down there when it hit 5 degrees. You will need rv antifreeze on hand in case you have a furnace issue so it can be winterized quickly.
I was there to help my son with some home remodeling issues but I will never RV in that environment again. Maybe a high quality RV would do better but I still wouldnt be there.
