Winterizing - frequent use

[Adony]

I plan on using my Wildwood T-25KS frequently this winter and am wondering about winterizing it between uses... The trailer has the Northwest Insullation Package installed. The local weather seldom stays below freezing for more than a day or two.. The fresh water tank is empty... If I keep a small electric heater set to come on a 50 degrees or so, drain the low point drains, and leave the cabinet doors open to the areas under the bathroom and kitchen sinks for heat, would this be sufficient to prevent problems? The heater would be in the bathroom where 90% of the trailers plumbing is... Ideas... suggestions... Anti freeze in traps?

You can leave a heater on 40, and water will not freeze. Cabinet doors open will prevent traps from freezing, and drain the low point drains, and the water heater. If the camper is in the sun, and it gets to 50 degrees inside during the day, pipes may never freeze. If you want a little insurance, blow them out with compressed air. Windshield washer antifreeze may be cheaper to pour in the drains, and before anyone gets upset, you aren't going to drink it, and it can't hurt the environment because you are spraying it all over the roadside anyway.

For the last several years we have given up with winterizing for the same reason, we use our rig year round. We keep an electric space heater going in the rig and the inside temperature at around 50 degrees. Keeping the air heated a bit also cuts down on moisture from the cold which is also destructive. In the outside plumbing bay where the water filter and other plumbing is I wrap a stringer of rope lights around everything and plug them into a digital temperature controller I had laying around that will turn them on automatically when the temps drop below 35 degrees.

I used to use it for my fermentation fridge when brewing beer. It is a digital control box with a temperature probe on a long wire. You can set it for heat or cool. When used for the fridge it was set for heat meaning when the inside temperature in the fridge got above the set point it would turn on the fridge and cool it back down to the set temp. This way I could keep my fermenting beer at exactly the temperature I wanted which is very important.

Inside the controller are contacts to attach wires to. I simply picked up a short extension cord and cut it in half, bared the wires and attached them to the terminal screws inside. It in effect becomes a switched extension cord that is temperature controlled. The controller plugs into a 110v outlet and then you plug your device into it. Very slick.

The one I used is called a Ranco ETC
