You didn't say how long the trip is. depending on the length of travel I would consider leaving it winterized until I got to the destination, then running the furnace should keep everything from freezing it has on my rig for winter camping. I would then re-winterize before leaving the campground for the trip home. Make sure you have a heated potable water hose.
