Me and the dw are staying in our cougar it's has the polar package. It was -30 last week for 3 days and -25 for rest of the week I burned 60lbs in 6 days I have skirting for my rig but did not have the slides wrapped. Now I have my slides wrapped and it has warmed up outside just my luck. I have had no problems with anything freezing but it's still early in the season lol. Oh and I run a small heater underneath just to be safe
