Winterizing a Wildwood X-Lite Model 185BH

Surely there is another option. Staying in an RV in any kind of cold weather is a poor proposition.
For starters they are not usually insulated sufficiently to keep up a normal temperature with the heater going full blast 24/7.
You might want to consider connecting a large propane tank to eliminate filling up the little tanks every few days. The gas is cheaper that way also.

I did 3 winters up north through snow, ice and lots of below freezing temps.
What worked for me:
1. skirt around the bottom, I used bi-fold Styrofoam underlayment that goes behind vinyl siding and taped the seams. I screwed 2x2 to bottom of trailer and matched the outline on the ground with 2x2 and secured with gutter spikes, I then stapled the foam to the strips. Blocking the airflow underneath pays off big.
2. Get a larger propane tank, source a longer pig-tail and hook up to one side of the regulator.
3. Get 1 or 2 1500 watt ceramic heaters, use them carefully making sure nothing that can burn gets too close. I had 30 amps and ran a second cord from a separate 20 amp circuit to allow both to run on high. Do when temps are below freezing back off on one of them so your furnace can run and put warm air in the plumbing bays.
4. Make yourself a heated fresh water hose, I used the everyday white water hose, got a matching length of heat tape and then wrapped it all in pipe insulation and then wrapped with electrical tape, kept my water going down to -15 degrees.

Be prepared for lots of moisture on the windows from humidity from breathing, cooking, showering etc. I kept the vent in the bathroom cracked constantly with a max-air cover over it. Position the trailer so that side with the most windows faces south-east, that way the sun from the morning until dark can give you a lot of free very warm solar heat.

Showers will have to be even quicker than normal as the water coming into the water heater will be colder than what you normally are used to.

It took some work but was doable.
