How to Winterize Your Trailer: A Step-by-Step Guide
Winter in East Tennessee brings crisp mornings and the risk of sudden freezes. With a sound winterize trailer plan, you can safeguard your RV and ensure it is ready for spring adventures. This guide covers every essential step, equipping you with the knowledge and confidence to protect your trailer throughout the cold months.
The Anatomy of a Winter-Ready Trailer
A winter-ready trailer requires attention to its most vulnerable parts: plumbing lines, water tanks, faucets, exterior seals, tires, and batteries. When temperatures fall, water can expand and split pipes or fittings, while cracked seals allow in moisture and cold air. Tires lose pressure, and batteries can freeze if not fully charged.
Problems that may arise include burst pipes causing subfloor flooding, split tank fittings leaking unnoticed, cracked roof seams leading to mold, flat-spotted tires, and dead batteries unable to hold a charge. Before winter sets in, perform a visual inspection. Check exposed water lines for bulges or discoloration, press gently on roof edges for soft spots, examine tire sidewalls for cracks, and ensure battery fluid covers the plates when serviceable.
To prepare:
– Drain and bypass the water heater
– Blow out or add RV antifreeze to the plumbing system
– Reseal roof vent flanges
– Inflate tires to recommended pressure and add covers
– Remove, clean, and trickle-charge batteries
– Lubricate slide rails and stabilizer jacks
– Lock doors and vents, allowing slight airflow with moisture absorbers
RV Antifreeze and Protecting Plumbing Lines
RV antifreeze is formulated for potable water systems, using non-toxic propylene glycol. Unlike automotive antifreeze, it is safe for drinking water lines and prevents pipes from freezing and bursting. The aim is to fill all low points in the plumbing, so water cannot freeze and cause damage.
Steps for Protecting Plumbing
– Drain the water heater and all tanks completely
– Engage the water heater bypass valve if available
– Use a hand pump or the onboard pump with a pickup tube in RV antifreeze
– Open each faucet, hot and cold, starting farthest from the pump until pink antifreeze appears
– Flush the toilet until pink fluid is visible
– Pour a cup into every drain to protect P-traps
– Pressurize the system, ensuring all lines are protected
Sealing Leaks and Strengthening Your Trailer
Tennessee’s fluctuating temperatures can damage seals, especially after thaw-refreeze cycles. Cracked or worn seals around roof vents, windows, and access panels permit moisture and cold to enter, threatening your trailer’s integrity.
Key areas to inspect include roof vent flanges and AC shrouds, corner moldings with old putty, window weep holes blocked by debris, slide-out toppers, bolt penetrations, and underbelly access panels. Inspect seals quarterly. Replace crumbly or brittle sealant with RV-rated lap sealant, and reinforce high-stress seams with butyl tape before caulking. Keep repair tape on hand for emergencies.
If roof work is not your preference, you can utilize professional services that provide comprehensive inspection and sealing.
Tires Brakes and Battery Care During Winter
Many RV owners focus on plumbing but overlook tires, brakes, and batteries. Cold temperatures reduce tire pressure, can cause flat spots, and diminish battery efficiency.
For tires, inflate to the maximum cold rating and use covers. Place the trailer on jack stands if storing for over 90 days. Adjust brake shoes and ensure connectors are moisture-free. Remove and clean batteries, test voltage monthly, and store on a smart charger above 12.4 volts.
Checklist for Winter Storage
– Record tire pressure
– Tighten lug nuts to specification
– Grease wheel bearings
– Test brake controller
– Note battery voltage each winter month
