When Should You Winterize Your RV in Chicagoland?

Written by Tony Pivo | Aug 31, 2026, 11:36:31 PM

If you own an RV in northern Illinois or Southern Wisconsin, don't put winterization off until the first hard freeze.

Once temperatures start dropping below freezing, any water left in your RV’s plumbing system can expand and damage fittings, faucets, valves, pumps, water heaters, and other components. Proper winterization protects those systems before cold weather can cause expensive damage.

At Solar Van Man®, we winterize motorhomes, travel trailers, fifth wheels, diesel pushers, truck campers, and camper vans for Chicagoland winters.

When Should You Winterize an RV in Chicago?

The safest answer is simple:

Winterize before sustained freezing temperatures arrive.

In Chicagoland, that usually means doing it well before late-fall weather becomes unpredictable. Waiting for the first overnight freeze is a gamble, especially if you store your RV outdoors or away from home.

If you know you are finished camping for the season, there is usually no advantage to waiting.

What Does RV Winterization Protect?

Your RV contains more plumbing than most owners realize.

A proper winterization protects the freshwater system, including:

  • Hot and cold water lines
  • Water heater
  • Water pump
  • Faucets and showers
  • Toilet and flush system
  • Low-point drains
  • Sink and shower traps
  • Water-fed appliances, when equipped

The objective is straightforward: remove or protect water anywhere freezing could cause damage.

Why RV Freeze Damage Gets Expensive Fast

A cracked fitting may sound minor until it is hidden behind cabinetry.

A damaged water pump, water heater fitting, toilet valve, or refrigerator water line can create leaks that are difficult to find and expensive to repair. Water damage can also spread into flooring, walls, and cabinetry before the owner realizes there is a problem.

Winterization is cheap compared with repairing freeze damage in the spring.

FREE Roof Inspection With Every Winterization

Every Solar Van Man® RV winterization includes a FREE roof inspection.

While the RV is in the shop, we inspect accessible roof areas for visible concerns such as:

  • Cracked or deteriorating sealant
  • Open seams
  • Failed lap sealant
  • Damage around vents and roof penetrations
  • Other visible conditions that may allow water intrusion

Winter storage is a bad time to discover that an RV also has a roof leak.

The inspection is intended to identify visible concerns before snow, ice, and winter weather make them worse.

What’s Included in Solar Van Man® RV Winterization?

Our winterization service includes the work necessary to prepare the RV’s plumbing system for freezing temperatures, including:

  • Freshwater system drained
  • Water heater drained and bypassed
  • Hot and cold plumbing winterized
  • Water pump, faucets, showers, and toilet winterized
  • Low-point drains and drain traps protected
  • Water-fed appliances winterized as equipped
  • Final plumbing-system winterization check
  • FREE RV roof inspection

Different RVs are built differently, so the exact procedure depends on the equipment installed in the vehicle.

Motorhomes, Travel Trailers, Fifth Wheels and Camper Vans

Solar Van Man® works on a wide range of RVs, including:

  • Class A motorhomes
  • Diesel pushers
  • Class B camper vans
  • Class C motorhomes
  • Travel trailers
  • Fifth wheels
  • Truck campers
  • Other RV and camper platforms

If it has an RV freshwater system and spends the winter in Chicagoland, it needs protection.
