8 Supplies for Winterizing an RV or Farm Hand Housing

When seasonal farm hands head home for the winter, their temporary housing—often a travel trailer, RV, or rustic cabin—remains behind to face the elements. Leaving these structures unprotected against freezing temperatures can lead to ruptured pipes, mold outbreaks, and thousands of dollars in spring repair bills. Investing a weekend into properly winterizing these living spaces ensures they remain safe, dry, and ready for next season’s crew.

Why Winterizing Farm Hand Housing Protects Your Farm

Farm hand housing is a critical asset that directly impacts the operational readiness of a small-scale farm. When spring arrives, there is no time to deal with flooded floors or ruined drywall while trying to get crops in the ground. Protecting these structures over the winter preserves capital and keeps seasonal labor transitions seamless.

Neglecting winter prep leads to preventable disasters like burst copper lines or cracked holding tanks. A single hard freeze can destroy an RV water heater or ruin cabin plumbing in a matter of hours. Taking preventative action now keeps overhead low and ensures that housing remains a welcoming, functional space for returning workers.

Assessing Your RV or Cabin Before the First Freeze

Walk through the housing unit before the thermometer dips below freezing to identify vulnerabilities. Look for worn window seals, gaps in the underbelly, and exposed pipes that run along exterior walls. Catching these drafty areas early saves money on heating bills and prevents localized freezing.

Test all appliances, water heaters, and slide-outs to ensure they are clean and functioning before shutting down utilities. Clear out any leftover food or organic matter that might attract mice seeking shelter from the cold. A thorough inspection sets a clear roadmap for the winterization process and highlights exactly which supplies are needed.

RV Antifreeze – Camco Premium RV & Marine Antifreeze

Water expands when it freezes, which easily splits plastic PEX lines and brass fittings. RV antifreeze fills these plumbing voids, lowering the freezing point of any remaining moisture to prevent structural damage. Unlike automotive antifreeze, this specialized formula is non-toxic and safe for potable water systems.

The Camco Premium RV & Marine Antifreeze is the ideal choice because of its reliable -50°F burst protection and high-grade, tasteless formulation. It uses a clean formula that does not leave behind nasty chemical tastes or odors once flushed in the spring. It is ready to use straight from the bottle without any messy dilution required.

Before purchasing, make sure to calculate the volume needed for the specific plumbing layout. Most standard RVs require two to three gallons, while larger cabins with extensive plumbing may need more.

• Burst Protection: Safe down to -50°F (-46°C)
• Composition: Propylene glycol-based, non-toxic formula
• Compatibility: Safe for brass, copper, and plastic plumbing systems

This product is essential for anyone winterizing an RV, camper, or cabin with a fresh water system. It is not suitable for automotive engine cooling systems, nor should it be used without completely bypassing the water heater first to avoid wasting gallons of fluid.

Blowout Plug – Camco Brass Quick Connect Blowout Plug

Clearing standing water from lines is much easier when using compressed air to push moisture out of the system. A blowout plug screws directly into the city water inlet, allowing a standard air compressor to clear the plumbing. This step ensures that no pockets of water remain to freeze and crack internal valves.

The Camco Brass Quick Connect Blowout Plug stands out due to its heavy-duty brass construction and convenient quick-connect design. Unlike cheap plastic plugs that easily cross-thread or crack under pressure, this brass fitting creates an airtight seal. The quick-connect stem snaps directly into standard air compressor hoses for one-handed operation.

Users must regulate their air compressor to no more than 30 to 40 PSI before starting this process. Excess pressure can blow apart delicate plastic plumbing connections hidden behind RV walls.

• Material: Solid lead-free brass
• Connection: Standard 3/4-inch garden hose thread to quick-connect air fitting
• Durability: Rust-resistant and reusable for multiple seasons

This tool is perfect for farmers who already own an air compressor and want a fast, reliable way to clear lines. It is not ideal for those without an adjustable air regulator, as unregulated high-pressure air will damage the plumbing.

Pipe Insulation – Frost King Foam Pipe Insulation

Exposed pipes underneath cabins or in unheated RV service bays are highly susceptible to cold drafts. Pipe insulation wraps these vulnerable lines in a protective thermal barrier, slowing down heat loss and preventing freezing. It is a simple, cost-effective layer of defense that works even during temporary power outages.

Frost King Foam Pipe Insulation is the industry standard for reliable thermal protection on small-scale farms. Made from durable polyethylene foam, it features a pre-slit design that slips easily over existing pipe runs. The material is highly flexible, allowing it to bend around tight corners without crimping or tearing.

Be sure to measure both the outer diameter of the pipes and the total length of the run before buying. Secure the seams with outdoor-rated tape or zip ties to prevent wind from peeling the insulation away.

• Material: Closed-cell polyethylene foam
• Wall Thickness: 3/8-inch standard insulation barrier
• Sizing Options: Available for 1/2-inch, 3/4-inch, and 1-inch pipe diameters

This insulation is a must-have for exposed plumbing runs beneath raised cabins or pier-and-beam farm housing. It is not designed for direct burial underground or for pipes that exceed temperatures of 200°F.

Heating Cable – EasyHeat AHB Water Pipe Heating Cable

When temperatures plummet far below freezing for extended periods, passive insulation alone is not enough. An electric heating cable runs along the pipe, actively generating heat to keep water flowing in sub-zero conditions. This is vital for farm hand housing that remains occupied during late-fall harvests or early-spring planting.

The EasyHeat AHB Water Pipe Heating Cable features a built-in thermostat that automatically turns the cable on at 38°F and off at 45°F. This smart operation saves electricity while ensuring the pipe never drops to freezing temperatures. The rugged outer jacket resists moisture and physical wear, making it tough enough for demanding farm environments.

This cable must be applied flat along the pipe rather than wrapped spirally to prevent overheating and potential fire hazards. It requires a constant, grounded 120V electrical outlet nearby to function properly.

• Thermostat Control: Automatic energy-saving temperature sensor
• Voltage: Standard 120-volt operation
• Safety Certification: UL Listed for peace of mind

This active system is perfect for keeping supply lines open to cabins or RVs that house workers during cold snaps. It is not suitable for dry plastic pipes unless they are kept filled with water during operation.

Moisture Absorber – DampRid Disposable Moisture Absorber

Closed-up RVs and cabins trap humidity, creating a breeding ground for mold, mildew, and musty odors over the winter. This moisture can ruin mattresses, rot wood paneling, and damage electronic components. Controlling indoor humidity is just as important as protecting the plumbing.

The DampRid Disposable Moisture Absorber uses natural calcium chloride crystals to attract and trap excess moisture from the air. These self-contained tubs require no electricity, making them perfect for off-grid cabins or winterized RVs with disconnected power. The clear container allows for quick visual checks to see when the crystals have fully dissolved into liquid.

Place several tubs throughout the housing unit, focusing on high-humidity areas like bathrooms, kitchens, and closets. Ensure they are placed on flat, stable surfaces where they cannot be knocked over by curious pests or wind drafts.

• Active Ingredient: Calcium chloride crystals
• Coverage: Up to 250 square feet per tub
• Lifespan: Lasts up to 45 days depending on humidity levels

This product is ideal for passive, long-term humidity control in unoccupied winter storage. It is not a replacement for a high-capacity electric dehumidifier in extremely wet, active-use environments.

RV Cover – ADCO Olefin HD All Climate RV Cover

Winter weather brings snow, ice, and intense UV rays that degrade roof seals, fade paint, and cause leaks. A heavy-duty cover acts as a shield, shedding water while allowing trapped moisture to escape. Without this protection, water can pool on flat roofs, freeze, expand, and create costly structural leaks.

The ADCO Olefin HD All Climate RV Cover features a highly breathable three-layer top panel that blocks water while letting interior condensation evaporate. The slip-seam strapping system ensures a tight, custom-like fit that prevents wind from whipping the fabric. Reinforced corners and durable side panels protect against tears from sharp gutters or ladders.

Accurate measurement of the RV’s total length—including bumpers, ladders, and spare tires—is critical before ordering. Installing the cover requires at least two people and a sturdy ladder to safely drape the fabric over the roof.

• Material: Heavy-duty Olefin top panel with polypropylene sides
• Protection: UV resistant, water-repellent, and highly breathable
• Fitment: Adjustable front and rear tension panels

This cover is excellent for protecting valuable travel trailers and fifth wheels parked in open, windy farm fields. It is not suitable for structures with sharp, unshielded protrusions that can puncture the fabric during high winds.

Hose Support – Camco Sidewinder RV Sewer Hose Support

Standard sewer hoses must drain completely to prevent standing waste from freezing and cracking the plastic line. A sloped support system lifts the hose off the cold ground, creating a gravity-fed decline that ensures complete drainage. This prevents messy blockages and protects the hose from being damaged by snow accumulation or pests.

The Camco Sidewinder RV Sewer Hose Support is constructed from lightweight, durable plastic that does not rust or corrode in wet winter conditions. Its unique accordion design expands easily to the desired length and curves around obstacles with ease. Deep cradles hold the sewer hose securely in place without the need for frustrating straps or ties.

Ensure the support is placed on relatively level ground to maintain a steady downward slope toward the dump station. Clean the support thoroughly before collapsing it for storage to prevent dirt from jamming the hinges.

• Material: Sturdy, rust-free plastic construction
• Design: Flexible accordion style with built-in handle
• Length Options: Available in 10-foot, 15-foot, and 20-foot spans

This is an essential accessory for any RV connected to a semi-permanent sewer hookup on the farm. It is not necessary for rigs that are completely drained and disconnected from sewer systems before winter storage.

RV Skirting – EZ Snap Direct Non-Drill RV Skirting Kit

The open space beneath an RV allows freezing winds to sweep under the floor, rapidly cooling the interior and freezing water lines. Installing a skirt seals this perimeter, trapping radiant heat and blocking bitter drafts. This simple barrier significantly reduces the energy required to keep the living space warm.

The EZ Snap Direct Non-Drill RV Skirting Kit offers a professional-grade wind barrier without damaging the RV’s exterior walls. It uses heavy-duty, marine-grade fasteners that attach via high-bond adhesive studs, eliminating the need to drill holes into the siding. The thick vinyl material is designed to withstand extreme cold without cracking or tearing.

Proper surface preparation is critical; the RV siding must be thoroughly cleaned with isopropyl alcohol before applying the adhesive studs. Allow the adhesive to cure fully before tensioning the heavy vinyl panels.

• Attachment: No-drill adhesive studs with heavy-duty snaps
• Material: Marine-grade, UV-treated vinyl skirting fabric
• Customization: Easily cut to fit around steps, hitches, and slide-outs

This kit is perfect for stationary farm hand RVs that will remain occupied or stored in wind-prone areas. It is not recommended for travelers who move their rigs frequently, as setup requires careful initial installation.

Step-by-Step Guide to Draining Your Water Lines

Begin by turning off the water heater and allowing it to cool completely before opening the drain plug. Open all interior faucets, including the shower and outdoor kitchen, to allow gravity to pull water down toward the low-point drains. Locate these drains underneath the rig or cabin and open them to let the bulk of the water escape.

Once gravity has done its work, close all faucets and attach the blowout plug to the city water inlet. Connect an air compressor set to a safe 30 PSI and open each faucet one at a time, starting with the closest and moving to the furthest. Run the air until only a fine mist, then dry air, escapes from each tap.

Do not forget to flush the toilet several times to clear the valve, and run the shower sprayer until it is completely dry. Finally, bypass the water heater and pump RV antifreeze through the lines using the water pump bypass kit. Pour a cup of antifreeze down every sink drain and toilet bowl to protect the P-traps and waste valves from cracking.

Crucial Maintenance Tasks to Perform Every Spring

When the ground thaws and spring planting begins, reversing the winterization process must be done systematically. Start by flushing the entire plumbing system with fresh water to remove all traces of pink antifreeze. Run clean water through every tap, shower, and toilet until the discharge runs completely clear and odorless.

Sanitize the fresh water system by adding a diluted bleach solution to the tank and pumping it through the lines. Let this mixture sit for several hours before flushing the system once more with clean water. Inspect all fittings, P-traps, and the water heater tank for any hairline cracks that may have developed despite winterization efforts.

Finally, inspect the exterior roof seals, slide-out gaskets, and window caulking for any winter damage. Re-lubricate slide-out mechanisms and check battery charge levels before welcoming seasonal workers back to the farm. Taking these steps ensures a smooth, safe start to the busy agricultural season.

Taking the time to properly winterize farm hand housing protects valuable agricultural infrastructure from costly cold-weather damage. With the right tools, insulation, and protective covers, these temporary living spaces will easily withstand the harshest winter elements. When spring arrives, a well-maintained cabin or RV ensures your seasonal crew can focus immediately on what matters most—the farm.
