We lived in our trailer, Sunnybrook 27FKS, while our house was being built. Had plenty of snow that year and temps into the teens. Heated, insulated water hose, heat at the park hose connection/spigot to prevent freezing, keep the lower cabinet doors cracked to allow heat to enter, you may need a heat source where the waterline enters the trailer, block off the underside, I put cot air mattresses under the slide out topper to to "puff it up" and insure runoff, aux heaters - oil filled or ceramic and watch your power useage. Use the outlet the microwave uses for a dedicated 15 amp power source. Dumped and flushed the holding tanks every seven to ten days. The closer the house got to completion, the smaller the trailer got. Hope these suggestions help.
