Winterizing your rig for a North Texas cold snap

← Back to the journal

North Texas winters are mild right up until they aren't. Most of the season sits above freezing, and then a front drops through and you get several days in the teens. That gap between "mostly fine" and "occasionally brutal" is exactly what catches people out.

Important distinction first: full winterizing — draining everything and running antifreeze through the lines — is for a rig you're storing. If you're living in yours, you need the opposite approach: keep the water flowing and keep it from freezing.

The water lines are the whole ballgame

Frozen pipes are the number one cold-weather callout at any park, and the damage isn't the ice — it's the split line you discover when things thaw.

• Heated water hose. The single best purchase you'll make. A standard hose is the first thing to freeze because it's fully exposed.
• Insulate the hose and the spigot even with a heated hose. Foam sleeve, pipe wrap, whatever you've got.
• Heat tape on exposed plumbing underneath, if your rig has any.
• Skirt the rig. Blocking wind under the trailer keeps the underbelly meaningfully warmer. Foam board, vinyl skirting, even hay bales — it works.

If a hard freeze is coming

For a genuine multi-day freeze, the safe play is to stop relying on the park's water line entirely:

• Fill your fresh tank and disconnect the hose. Run off the pump for the duration.
• Drain and store the hose somewhere it can't freeze solid.
• Leave cabinet doors under sinks open so interior heat reaches the plumbing.
• Let a faucet drip if lines are exposed — moving water is much harder to freeze.
• Keep a little antifreeze in the gray and black tanks, and don't leave valves closed on a full tank.

The fix takes an hour. The repair takes a week and a plumber who's already booked solid.

Heat and propane

Your furnace will run harder than you expect, and it's what keeps the underbelly warm — space heaters heat the room but not the plumbing.

• Check your propane level before the front arrives, not during. Everyone refills at once and suppliers run out.
• Have a second tank if you can. Running dry at 2am in a freeze is a bad night.
• If you use electric space heaters, know your amp limits — a heater plus everything else is how you trip a pedestal breaker.
• Never use a propane cooking appliance as a heat source indoors. That's a carbon monoxide risk, full stop.

Test your CO and smoke detectors

Winter is when you're running combustion heat in a sealed space, which makes this the season those detectors actually matter. Test them and replace the batteries at the start of the cold months. It takes two minutes.

Condensation, the quiet problem

A sealed rig with people breathing and cooking in it produces a surprising amount of moisture, and in winter it condenses on every cold surface. Left alone, that becomes mold in the corners and behind the mattress.

• Run the vent fan while cooking and showering.
• Crack a roof vent — losing a little heat is worth it.
• A small dehumidifier earns its keep, as do moisture absorbers in closets.
• Pull the mattress off the platform occasionally and let it breathe.

The rest of it

• Reseal any roof or window gaps in the fall — cold finds every one of them.
• Insulated window covers or even reflective panels cut heat loss a lot for very little money.
• Keep the slides clear; ice on a slide seal is how seals tear.
• Have a plan for a power outage — blankets, a charged power bank, and a way to get warm elsewhere.

Timing

Do the setup work in November while it's pleasant. Everything on this list is easier at 60 degrees than at 25 with a norther blowing through, and the forecast around here rarely gives you more than two days' notice.
