RV Winterization Tips for Texas: What You Need to Know

Texas has a reputation for warm weather, and most of the year that reputation is well-earned. But North Texas winters — including the Fort Worth area — can deliver hard freezes, ice storms, and the occasional multi-day cold snap that catches unprepared RVers off guard.

The 2021 winter storm that knocked out power and water across Texas was a stark reminder: even in the South, winter preparation matters. For RVers staying at a Fort Worth RV park through the fall and winter months, a few smart steps can protect your rig, your pipes, and your comfort when temperatures drop.

Understanding North Texas Winters

Fort Worth sits in USDA Hardiness Zone 8a, which means average winter lows in the 15–20°F range are possible, though not typical. Most winters bring a handful of nights below freezing, occasional ice storms, and rare but serious hard freezes.

What makes Texas winters tricky for RVers isn't the depth of the cold — it's the unpredictability. A week of 65°F weather can be followed by a sudden overnight drop to 20°F. If you're not prepared, that swing can freeze your water lines before you have time to react.

The good news: full winterization (the kind you'd do in Minnesota before storing your rig for six months) isn't necessary for Texas. What you need is cold-snap preparedness — a set of habits and equipment that protect your rig during the 5–15 nights per year when temperatures dip below freezing.

Protecting Your Water Lines

Frozen water lines are the most common and most expensive winter RV repair. Water expands when it freezes, and that expansion can crack PVC fittings, split hoses, and damage your water pump — repairs that can run $200–$1,000 or more.

Know Your Freeze Threshold

Water in exposed pipes begins to freeze when air temperatures drop below 32°F and stay there for several hours. The risk increases significantly below 28°F. In Fort Worth, most freeze events are brief — one to two nights — which means you have options short of full winterization.

Disconnect and Drain When a Hard Freeze Is Forecast

When temperatures are forecast to drop below 28°F for more than a few hours, the safest move is to disconnect your water hose from the spigot and drain it. Store the hose inside your rig or in a heated compartment overnight.

Switch to your onboard fresh water tank for the duration of the freeze. Your tank is insulated by the rig's underbelly and is far less vulnerable than an exposed hose.

Insulate Your Water Hose

For milder freezes (28–32°F for a few hours), insulating your water hose can be enough. Foam pipe insulation tubes from any hardware store slip over standard RV water hoses and provide meaningful protection. Wrap the spigot connection as well — that's where freezing typically starts.

Heat Tape for Persistent Cold

If you're staying through a particularly cold stretch, self-regulating heat tape (also called heat cable) wrapped around your water hose and plugged into shore power will keep water flowing even in sustained freezing temperatures. It's inexpensive, easy to install, and draws minimal power.

Keep Your Tanks From Freezing

Your gray and black tanks are also vulnerable in hard freezes. A few strategies:

• Tank heaters: Aftermarket electric tank heaters attach to the underside of your tanks and keep them above freezing. Many newer rigs have them factory-installed.
• Dump before a freeze: If a hard freeze is coming, dump your tanks beforehand so there's less liquid to freeze.
• Add RV antifreeze to your black tank: A cup of RV-safe antifreeze (pink, not automotive) in your black tank helps prevent freezing and keeps the sensors working.

Keeping Your Rig Warm

Skirting

RV skirting — panels that enclose the space between your rig's frame and the ground — is one of the most effective ways to retain heat in cold weather. It traps warm air under the rig, protects your tanks and underbelly plumbing, and can meaningfully reduce your heating costs.

Foam board skirting is inexpensive and easy to cut to fit. Vinyl skirting looks cleaner and is more durable. For Texas winters, even a basic foam board skirt makes a noticeable difference during cold snaps.

Seal Drafts

Cold air infiltrates RVs through slide-out seals, door gaskets, and any gaps around utility connections. Walk around your rig and feel for drafts. Replace worn slide-out seals and door gaskets, and use foam weatherstripping tape to seal any gaps.

Window Insulation

Single-pane RV windows are poor insulators. Reflectix (a foil-faced bubble wrap insulation) cut to fit your windows and held in place with suction cups provides a significant thermal barrier. It's not pretty, but it's effective on the coldest nights.

Vent Covers

Roof vents are another major source of heat loss. Foam vent insulators (available at any RV supply store) drop into the vent opening from inside and block cold air. Remove them before running your roof AC in warmer weather.

Heating Your RV Efficiently

Propane Furnace

Most RVs come with a propane furnace, and it's your primary heating source in cold weather. Make sure your propane tanks are full before a cold snap — you don't want to run out at 2 AM when it's 25°F outside. A 20-pound propane tank typically lasts 3–5 days of regular furnace use in cold weather.

Electric Space Heater as a Supplement

A small electric space heater (1,500 watts) can supplement your propane furnace and reduce propane consumption. On a 30-amp service, you can run a space heater alongside your other appliances — just be mindful of your total draw. On a 50-amp service, you have more headroom.

Never use an unvented propane or kerosene heater inside your rig — the combustion byproducts (including carbon monoxide) are dangerous in an enclosed space.

Heated Mattress Pad

A heated mattress pad is one of the most energy-efficient ways to stay warm at night. It draws far less power than a space heater and keeps you comfortable without running your furnace all night.

Staying at Settlers Haven Through the Winter

Settlers Haven Mobile Home & RV Park in White Settlement is a year-round park, and we have long-term guests who stay through the winter months. Our full hookups (30/50 amp electric, water, sewer) give you everything you need to stay comfortable, and our on-site management team is available if you have questions or concerns during a cold snap.

A few tips specific to staying at our park during winter weather:

• Monitor forecasts: The National Weather Service Fort Worth office (weather.gov/fwd) provides excellent local forecasts and issues freeze warnings well in advance.
• Communicate with management: If a hard freeze is forecast, let us know. We can advise on site-specific considerations and help coordinate if there are any utility concerns.
• Have a backup plan: In the event of an extended power outage (rare but possible, as 2021 demonstrated), know where you'll go if the park loses utilities for more than a day.

Winter in Fort Worth is mild most of the time — but being prepared for the exceptions is what separates a comfortable stay from a costly repair. A few hours of preparation before the cold season pays dividends all winter long.
