How to Store a Truck Camper in the Winter?

When frigid temperatures arrive, every truck camper owner should take steps to properly winterize and store their beloved home on wheels. Taking the time to thoroughly prepare your camper for storage during winter is crucial to avoiding damage from freezing, moisture, pests and neglect over the long off-season.

How to Store a Truck Camper in the Winter? This comprehensive guide will provide truck camper owners with tips and best practices for securing their investment through harsh weather and making sure it survives the cold months unscathed.

We’ll cover properly winterizing plumbing and appliances, finding the optimal storage facility or location, maintenance and security measures to take, and what to do when it’s finally time to bring your rig out of winter hibernation.

Follow these key guidelines for storing your camper over the winter so it remains in pristine condition, ready for more smooth camping trips when sunny skies return.

Prepare the Camper for Storage

Prepare the Camper for Storage

Before tucking your truck camper away for its long winter’s rest, preparatory steps need to be taken to prevent damage while stored. This includes winterizing sensitive systems, charging the battery, exterior care and thorough cleaning.

Winterize the Plumbing System

One of the most important parts of winter camper prep is properly winterizing the plumbing system. Freezing temperatures can cause pipes to burst and tanks/lines to crack if any water remains inside.

This requires draining all potable water from the sinks, toilet, water heater, pumps and tanks. Opening low point drains and faucets allows liquids to drain out. Use compressed air to remove remaining droplets stuck in the lines.

Then pour RV antifreeze into the sinks, toilet and drains which displaces all remaining moisture. Running antifreeze through the entire system down to the tanks protects pipes through even frigid conditions. Take care to follow your owner’s manual guidelines for winterization.

Winterize Appliances

In addition to plumbing, appliances need prepped to prevent issues. Clean out and defrost the refrigerator fully. Prop doors open so air can circulate. On gas/electric models, turn off propane and disable auto-ignition.

For the water heater, drain all water and bypass the water lines going to the heater. Empty and clean the holding tanks thoroughly to avoid odors and staining. Cover exterior vents to keep pests out.

Disconnect and Charge Battery

Fully charge the battery before winter storage and disconnect it to prevent power drain over time. Remove it and store in a location that won’t freeze. A temperature-stable basement is ideal.

You can also use a trickle charger to maintain the battery while in storage if removal isn’t feasible. Clean corrosion off terminals and wash the battery exterior before storage.

Clean and Dry the Interior

Give your truck camper a thorough interior cleaning before storage. Wash any bedding and floor mats. Use cleaners on countertops, cabinets, flooring and bathroom surfaces.

Remove all perishable food items from the refrigerator and cabinets to avoid attracting pests. Take out the trash and do a final vacuum. Place baking soda boxes and moisture absorbing packs in cabinets to keep the interior air fresh and dry.

Exterior Care and Protection

Before parking your camper, wash and wax the exterior for protection. Inspect door, window and roof seals and re-caulk if any cracks appear. Check that vents and caps are secure.

Lubricate door hinges and locks so they don’t freeze up. Consider covering air conditioner and vulnerable roof areas with protection designed for stored RVs.

Choose the Best Storage Location

Choose the Best Storage Location

Where you store the camper for winter is an important decision to keep it protected from the elements. Assess these common options truck camper owners utilize during cold months:

Heated Garage or Pole Barn

Storing in an enclosed, climate controlled garage or barn is ideal if space allows. Ensure the building is unheated to avoid moisture buildup inside the parked camper. But the enclosure protects from precipitation, sun damage and pests while making it easy to access for maintenance.

Self-Storage Unit

Indoor self-storage facilities are another good option that provide security and shelter at an affordable price. Look for units that are clean, dry and pest-free with 24/7 access. Have electrical hookups to allow charging batteries and running dehumidifiers.

Campground Seasonal Site

Some campgrounds offer discounted rates for seasonal winter camper storage. This allows access to electrical, water hookups and bathhouses so periodic maintenance is convenient. Security may be more limited.

Your Property

If indoor parking isn’t available, storing in a level driveway or yard spot works too. This leaves the camper more exposed to the elements so take extra precautions like tire covers, roof protection and pest control measures. Also allows easy access for periodic inspection.

Take Added Precautions Outdoors

If forced to store your truck camper outside due to space constraints, take extra steps to protect it from Old Man Winter’s wrath:

Use a Breathable Cover

Invest in a fitted, breathable cover intended for RV storage use. Ensure it is properly secured and allows adequate ventilation while shedding precipitation. Periodically clear heavy snow or debris accumulation.

Install Skirting

To protect the underside from wind, snowdrifts and rodents, install custom skirting around the base. Insulation boards or canvas skirts divert wind and retain heat beneath.

Elevate on Supports

Place blocks or jackstands under the frame to slightly elevate and take pressure off tires. This prevents flat spots from forming during months of disuse.

Attach Stabilizer Wings

Using stabilizer wings or support jacks at the four corners helps prevent shifting from frost heaving and winds over winter.

Monitor Interior Humidity

Regularly check under the cover for condensation buildup. Use vent fans, dehumidifiers and moisture absorbers inside to manage interior humidity in cold months.

Ongoing Maintenance is Crucial

Don’t just park and forget your stored camper for winter. Performing regular maintenance checks is vital to catching issues early and preventing costly damage:

Monthly Inspections

Do a thorough walkaround at least monthly. Look for any water intrusion issues, leaks, pest infiltration or mold growth. Check seals around windows, vents and openings. Ensure supports are stable. Clear snow or debris from roof.

Check Tire Pressure

Tire pressure drops over time when not in use. Inflate to recommended cold weather pressures before storage and recheck monthly. Top off as needed.

Recharge Battery

If stored onsite, disconnect and recharge the battery every 4-6 weeks to maintain optimal charge. Clean terminals each check. Or utilize a trickle charger to automatically maintain.

Start and Run Generator

Exercise the generator monthly by starting and letting run for 15-20 minutes following manufacturer guidelines. This lubricates parts and prevents stagnation.

Rodent Prevention

Place traps and bait stations around the perimeter. Use moth balls, ammonia-soaked rags or cotton balls with peppermint oil as deterrents inside. Seal any openings with mesh, caulk or foam.

Remove from Storage Properly

When the last frost thaws, excite your camper from its long winter’s nap using these tips:

Full Inspection

Before loading up, do a complete exterior/interior inspection looking for any damage or leaks incurred during storage. Check the underside for critters or nests.

Systems Check

Plug into shore power and test appliances, lights, furnace, generator and electrical. Inspect the propane system for leaks and test stove/fridge ignition.

Charge and Install Battery

Fully recharge the battery that was stored separately and reinstall it. Ensure it holds a complete charge before tripping.

De-winterize Plumbing

Drain antifreeze from lines and tanks, close bypass valves and reconnect water supply. Turn on pumps and test for leaks at all faucets and fixtures before drinking.

Wash and Disinfect

Wash down the exterior, roof, slides and underside that were exposed to the elements. Disinfect and deodorize the interior too.

Address Any Issues

Fix any pest, water damage or mechanical problems found during inspection before hitting the road again. Repair seals or caulk as needed.

Practice Runs

Do a couple shakedown trips close to home before heading out on lengthy journeys. This helps identify any issues missed during revival.
