Hi all, new member and new RV'er here. My wife and I recently purchased a Keystone Passport Ulrta Light that is an extended season trailer. My question is this: I am planning on going camping over the New Years weekend in NW Oregon. The average temps at that time of year seem to be around 40f in the day, dropping to mid-high 20's at night. From what I have read here, I will be adding anti freeze to gray and black holding tanks and run off of my fresh water tank. The thing that I am concerned about is the fresh water tank drain. It's a small hose, probably 3/8" ID hose with a plastic cap on the bottom, it sticks down about 4 or 5" below the bottom of the trailer. I am worried about the water freezing in that hose and breaking it, I would appreciate some feedback from the seasoned RV'ers here, thanks.

No need to waste your money on antifreeze in the holding tanks. Biggest worry is going to be propane. Be sure the gas tanks are full, you have lots of blankets, warm clothes, and lots of power. Youll need them all.

Thanks for the replies, good to know about the anti freeze. We are going to be staying at a campsite that has full hookups, so as long as there are no problems at the campground, power shouldn't be an issue. I can carry 40 lbs of propane in 2 tanks, hopefully that will be enough.Any thoughts on the fresh water drain tube? Should I put some kind of insulation over it just in case?

If its like my passport, the cap is the valve. When you unscrew it water comes out. I would try to put some kind of insulation over that hose and hope that the warmer water in the tank helps keep it from freezing. other option is to install a valve as close to the top of drain hose or put one inside the trailer. The later would be a pain as I assume your water tank is under the bed and pump and fittings are beneath the side nightstand. This involves removing the top cover to access.
