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.

My trailer also has a drain tube for the fresh water, maybe sticks out 3" from the belly. the valve for the drain is inside the cabin of the trailer, so its just an empty tube sticking "outside" - nothing to freeze as long as the heat's on inside.

where is the valve for your drain, is it inside or outside your trailer?

Yes, mine has the cap also, no valve that I can see. As soon as I remove the cap, water drains out of it.
I was thinking about going to Home Depot and getting some of that water heater pipe foam insulation and putting it over the hose just as a precaution.
I'm not sure exactly where the tank is in relation to the bed, my TT has the front bedroom with rear living room, 24 1/2'. The fresh water fitting on the outside of the trailer is about where the bathroom sink is.
I may be being a bit over cautious, but I just don't want to have problems with my new trailer, especially ones that I could've possibly avoided.

I will try looking inside to see if I can find a valve anywhere, thanks for the advice.

I read in another thread that some TT's have the ducting from the heater going under the floor to warm the tanks, does anyone know if the Passport has this type of heating? My trailer has ducted heat, one duct in the bedroom at the foot of the bed, one in the panel under the fridge right next to the power panel where the furnace is, and another duct in front of the kitchen sink cabinet.
The air from the round outlet at the furnace blows lots of air but not too much comes out of the floor ducts. I read where someone suggested that some of the air is diverted to the tanks. Have any of you heard of this or have experience with this? Thanks again.

As someone who has spent more than his share of single digit TT living I have never had a problem with the drain tubes. I'm sure they freeze solid but I have never had an occasion to drain in freezing weather. I have other posts that cover cold weather living in a TT.

My 15 Keystone Premier has a heated underbelly. I'd think if you were at full hookups, were actively using the trailer and had the heat on when it was below freezing that you shouldn't have any issues. They also sell a heated hose if you wanted/needed to hook up to water at the campground. They go for about $100. I've never used one, but considered getting it if I took my TT to MD in December. If yours is an "extended season" trailer, I'm sure you have a heated underbelly as well. Check your paperwork or the brochure. I'd bet you have that option.
