I like easy, so here goes! I was born and raised in Florida and know enough to stay there in the winter, so that is the reason I have never had to winterize. But I do sanitize my freshwater tank and when I do drain it, I tilt the trailer to the curb side which is were the drain pipe exits the freshwater tank and I remove the outside shower head, turn the shower on and insert the hose into a piece of PVC pipe to move the water away from the trailer when I am at home. You could run it into your drain hose if your campsite has a sewer connection. And I wouldn’t have any qualms with opening the freshwater drain and driving down the road if the weather cooperates. I often dump my freshwater during the last few hours of driving home. That probably wouldn’t work in freezing weather. On the other hand it may be safer to have a 1/2 of tank of water, which would be less likely to freeze.
