The Cost to Winterize a Camper

As winter approaches, protecting your camper from the cold is a necessity for the majority of adventure vehicle owners. That’s right. If you live or travel anywhere in which the temperature drops below 32 degrees, even for a night or two, you need to take action. This process of protecting a vehicle from cold-caused damage is fittingly called winterization. Fortunately, it can be done by the professional and amateur alike. For the DIY-ers out there, here’s a quick rundown on all necessary steps as well as the typical cost to winterize a camper.

Initial Steps towards Winterization


First, begin with routine maintenance. Clean the trailer top to bottom, inside and out before closing and retracting all components. Inspect any and all sealants to ensure exclusion of unwanted moisture.

By the same token, try to maximize airflow by any means necessary internally. Make sure to remove all items from the fridge, separate interior cushions, and place a few containers of moisture-gathering beads throughout the trailer. These will run you about $8 a pop.


After that, clean the tires and lubricate all grease fittings on the axle hubs. Set tire pressure to max indicated on the tire sidewall and chock wheels to prevent movement. Each chock will run about $8 each as well. For absolute best care, you may wish to invest in waterproof tire protectors at around $5 per tire.


Disconnect the battery, unplug the AC, and move the battery into a safe environment while the vehicle sits dormant.


Finally and most importantly, drain the water out of your vehicle. Most adventure vehicles, including those that TAXA makes, do not come with insulated pipes. Thus, camping or even storing a vehicle in freezing temperatures requires draining the water tanks and lines to completion.

To accomplish this, drain the fresh water tank/grey water tank, open all interior water fixtures, disconnect exterior fixtures, turn any interior drainage valve open, and drain the water heating system if applicable all by following instructions listed in your manual.

Cost to Winterize Camper Approach #1 – Antifreeze Kit

In order to finish protecting your pipes, there are two commonly used methods. The first of which relies solely on running antifreeze through not only your pipes but all fixtures and internal lines.

Essentially, pump antifreeze into your grey/freshwater tank. Then, open fixtures one by one until antifreeze makes its way through that outlet.

The only equipment needed is a couple gallons of antifreeze ($15 each, less if you’re thrifty) and a pump, hose, and adapter ($15 kit).

Here’s an excellent demonstration of the approach from All About RV’s.

Year-over-Year Cost: $30

This method is very similar to the first. However, it relies on an air compressor to expel residual water from lines before antifreeze comes into play. Essentially, hook up the compressor to each tank and blow out air at a super low pressure. Then, head on inside and open fixtures one by one until water spurts out.

Upon ridding lines of any water, finish the process by pouring a small amount of antifreeze down each drain and into fresh and grey tanks.

This will require a larger purchase of a light duty air compressor along with an adapter (roughly $150). However, you will use a fraction of the antifreeze compared to the first method. It’s your call depending on how many times you plan on winterizing and/or using the compressor.

Once again, here’s a demonstration of the approach from All About RV’s.

Cost to Winterize Camper Approach #3 – Service Professional

If you’d really prefer to have a professional do the job, winterizing is a common service offered by mechanics.

Estimated Yearly Cost: $125


Winterizing is a vital step towards preserving the functionality of your adventure vehicle during the winter months.

Most of this process is simple and completely free. The rest is fairly inexpensive.

You can expect to pay around $90 upfront and $50 year-over-year by choosing approach 1 or around $200 upfront and only $30 year-over-year by choosing approach 2.

An annual winterization appointment with a service professional is also an option for around $125.
