How to Winterize Your RV Before Storing in Henderson County, TX

August 5th, 2026


If you're getting ready to park your RV for the season, taking a few extra steps before it goes into storage can save you from a rough surprise come spring. McKamy Storage in Caney City works with plenty of RV owners around Cedar Creek Lake who are getting their rigs ready for winter, and a little preparation before RV storage goes a long way toward protecting your investment through Henderson County's cold spells.

Why Winterizing Matters Even in Texas

It's easy to assume Texas winters are too mild to worry about freeze damage, but Henderson County still sees real cold stretches. The average first freeze arrives around November 26, and temperatures can dip well below freezing on the coldest nights of the season. Water left sitting in pipes, tanks, or lines can freeze and expand, which is exactly the kind of damage that catches RV owners off guard when they open things back up in spring.

Beyond freeze protection, winterizing also helps prevent mold, pest issues, and general wear that can build up in an RV that's sitting unused for weeks or months at a time.

Key Steps to Winterize Your RV

Start with the water system. Drain the fresh water tank, water heater, and all water lines completely, then run RV antifreeze through the system to protect against any remaining moisture freezing inside the pipes. Don't forget the toilet and any exterior showers, since these are easy to overlook.

Next, take care of the battery. Either remove it and store it somewhere temperature-stable, or keep it connected to a trickle charger if power is available at your storage location. A battery left to fully drain over winter often won't hold a charge properly once spring arrives.

Clean the interior thoroughly before closing it up, since food residue and moisture left behind are what attract pests and encourage mold growth. Cover tires or use tire covers to protect against UV exposure and temperature swings, and check tire pressure before storing so they're not sitting under- or over-inflated for months.

Henderson County's Winter Weather

Henderson County has a humid subtropical climate, which means winters are generally mild compared to much of the country, but they're not without genuine cold snaps. Average lows in January run in the mid-30s, and the average last freeze doesn't arrive until around March 11, meaning your RV could be exposed to freezing temperatures for several months if it's not properly winterized.

McKamy Storage's location on TX-198 puts it within easy reach of Malakoff, Gun Barrel City, Mabank, and Athens, as well as the upscale lakeside communities of Long Cove, Pinnacle Point, and Star Harbor near Cedar Creek Lake. For boaters and RV owners coming off the lake for the season, that makes it a convenient spot to winterize and store in one trip.

Why RV Storage at McKamy Makes the Process Easier

McKamy Storage offers outdoor RV, car, and boat parking on a fenced and gated property with 24-hour access and video surveillance, so you can finish winterizing on your own schedule rather than working around office hours. Power outlets are available on-site as well, which can help if you're using a trickle charger to maintain your battery over the winter months.

Keep in mind that tenant insurance is required for RV and boat parking spaces, so it's worth having that documentation ready when you reserve your spot. It's also worth checking whether a breathable RV cover makes sense for your setup, since a well-fitted cover can add another layer of protection against sun exposure, tree debris, and moisture without trapping humidity underneath the way a tarp sometimes can.

Getting Your RV Ready for the Season Ahead

Winterizing your RV before storage doesn't take long, but skipping it can lead to costly repairs once warmer weather returns. Draining the water system, protecting the battery, cleaning the interior, and prepping the tires are all worth doing before your RV sits for the winter.
