A Hill Country winter can serve up a sunny afternoon, a sharp north wind after dark, and an overnight freeze before breakfast. Preparing RV for winter stays is less about turning your rig into a fortress and more about staying ready for those quick changes. A few practical steps can protect your plumbing, keep the living space comfortable, and let you enjoy the quiet side of Texas camping.
Start With the Weather, Not the Calendar
Winter in Central Texas is usually mild, but mild does not mean predictable. Daytime temperatures may feel comfortable enough for a hike or a ride into Bandera, while a passing cold front can bring freezing temperatures overnight. Check both the daily high and the expected low, especially when a front is moving through.
Your RV setup should match the forecast and your plans. If you are staying put for weeks or months, it makes sense to use an insulated water hose, a heated hose cover, or heat tape rated for RV water lines. If you are only visiting for a weekend and a hard freeze is expected, disconnecting the fresh-water hose at night may be the simpler option. Fill your fresh tank first if you have the capacity and are comfortable using the onboard pump.
Do not wait until pipes are already frozen. Water expands as it freezes, and a split fitting or cracked hose can create a messy surprise when temperatures climb again. Open cabinet doors under sinks so warm interior air can reach nearby plumbing, and keep an eye on outside compartments where water lines are exposed.
Preparing Your RV for Winter Stays at the Site
A well-chosen, level site makes cold-weather living easier. Before settling in, check that your sewer hose has a steady downhill run without low spots. Those dips can hold water and become a problem in freezing weather. Use proper supports if needed, but avoid stretching hoses so tightly that fittings are under strain.
Once you are connected, inspect your water connection, sewer connection, and electrical pedestal before the weather turns. A slow drip at the spigot or a loose sewer fitting is easier to fix on a pleasant afternoon than in the dark with cold hands. Keep a small flashlight handy near the door, not buried in a storage bay.
Space around the RV matters, too. Leave room to reach compartments, propane bottles, and utility connections. You may want to position your entry mat, chairs, and outdoor gear so you are not stepping around them during a wet or windy morning. In the Hill Country, a hard rain can follow a cold front, so good drainage and a flood-free location offer extra peace of mind.
Keep Water Flowing Without Wasting Energy
There is no single freeze-protection method that fits every RV. Your rig’s plumbing layout, insulation, tank placement, and whether you have an enclosed heated underbelly all make a difference. Consult your owner’s manual before adding heat tape or modifying any water line.
For a light freeze, keeping the interior heated and opening sink cabinets may be enough for many rigs. For temperatures expected to stay below freezing for several hours, protect the hose and the exposed connection at the pedestal. Foam pipe insulation can help, but it does not create heat on its own. A purpose-built heated hose is often the more dependable choice for an extended stay.
If the forecast calls for a deeper freeze, consider disconnecting from city water and relying on your fresh tank overnight. Drain the hose fully, store it where it will not freeze, and reconnect after temperatures rise. This approach takes a little more effort, but it removes one of the most vulnerable parts of an RV water system.
Avoid the temptation to leave water running continuously unless your RV manufacturer specifically recommends it for your setup. It wastes water, can overfill your gray tank if a drain is closed, and does not protect every section of your plumbing.
Heat the RV Safely and Evenly
Your furnace is designed to heat the coach and, in many RVs, help protect underbelly plumbing. Keep it in good working order before you leave home. Test the furnace, replace weak batteries in your thermostat if applicable, and make sure exterior vents are clear.
Electric space heaters can be useful for taking the edge off a bedroom or living area, but they need care. Use a heater with tip-over and overheat protection, place it on a solid floor away from bedding and curtains, and plug it directly into a proper outlet. Never run a space heater through a lightweight extension cord or a crowded power strip.
A 30-amp RV has less electrical breathing room than a 50-amp RV. Running multiple heaters alongside a microwave, coffee maker, or electric water heater can trip a breaker quickly. At a full-hookup park with both 30-amp and 50-amp service available, use the service your RV is designed for and learn what your electrical system can comfortably handle.
Propane heat is a dependable part of winter RV life, so check your tanks before a cold spell. Keep an eye on the fuel level rather than waiting for the furnace to quit in the middle of the night. Carbon monoxide and propane detectors should be tested regularly, and fresh batteries belong on your winter-prep list.
Fight Condensation Before It Feels Like a Leak
Warm people, cooking, showers, and cool windows create moisture. Over time, condensation can collect on glass, metal frames, and inside cabinets along exterior walls. Left alone, it can lead to musty smells, damp bedding, or mildew.
Use roof vents briefly while cooking and showering, even when it is chilly. A small dehumidifier may help during a longer stay, particularly in a smaller trailer or when two people and a pet are spending more time indoors. Wipe down wet window frames in the morning, and avoid blocking every source of ventilation in an effort to hold heat.
Insulated window coverings can make the RV feel noticeably warmer at night. They also reduce condensation, although they will not eliminate it completely. The trade-off is less natural light, so many winter guests put them up after sunset and remove them when the day warms.
Give the Outside of Your Rig Some Attention
Cold weather reveals worn seals, loose caulking, and tired weatherstripping. Walk around the RV before your stay and look closely at roof edges, window seals, storage doors, and slide-out gaskets. A small draft can make one corner of the coach uncomfortable, and a small leak can become a much bigger repair after repeated rain.
Skirting can help reduce wind under the RV, especially for longer stays. It is not necessary for every Texas winter night, and poorly installed skirting can trap moisture or blow loose in strong winds. If you use it, leave access to important valves and compartments, and inspect it after storms.
Bring a basic cold-weather kit that stays easy to reach:
- Insulated or heated fresh-water hose and spare washers
- Foam insulation for exposed connections
- A compact flashlight, work gloves, and a small tool kit
- Extra propane, furnace-safe batteries, and a weather radio or charged phone
- Absorbent towels for condensation, wet shoes, or a minor plumbing drip
Make the Stay Comfortable, Not Just Protected
Winter RVing should still feel like time away, not a maintenance project. Keep a pair of dry shoes by the door, layer blankets on the bed, and make room for the things that make a cool evening pleasant – coffee, a good meal, or a quiet view from your window.
For seasonal guests, routine is your friend. Check the forecast each evening, glance at utility connections during your morning walk, and refill propane before the gauge is near empty. Those small habits make sudden cold snaps far less stressful.
At Pomarosa RV Park and Homestead, spacious full-hookup sites and a peaceful Hill Country setting give winter guests room to settle in without feeling crowded. Whether you are a Winter Texan staying awhile or passing through on Highway 16, a prepared RV lets you spend less time watching the thermometer and more time enjoying where the road brought you.
When the next cold front rolls across the Hill Country, let your preparations do the work. Put on a warm layer, check your connections, and enjoy the kind of quiet evening that makes an RV stay feel like home.
