Extend Your Adventure: Four Season & Winter Ready RVs

What Makes an RV Truly "Four-Season"?

Many RVs claim to be "extended season," but surviving a light autumn frost is very different from weathering a true Canadian winter. A legitimate four-season camper requires heavy-duty engineering from the chassis to the roof. Here is what sets them apart:

Fully Enclosed & Heated Underbellies

The most vulnerable part of any RV in the winter is the plumbing. Four-season models feature fully enclosed underbellies that are actively heated by dedicated furnace ducts. This creates a pocket of warm air that prevents your fresh water, grey water, and black water holding tanks—as well as your water lines—from freezing solid.

Superior Insulation & Radiant Barriers

A standard summer camper will bleed heat rapidly. Winter-ready RVs utilize thick, double-layered fiberglass batt insulation in the roof and floors, paired with double-sided reflective radiant foil barriers. This "thermos effect" traps your furnace heat inside during the winter and reflects the sun's harsh rays away during the summer.

High-Capacity Furnaces & Dual-Pane Windows

To combat extreme cold, four-season RVs upgrade to massive 35,000 BTU high-output furnaces. Many also offer optional dual-pane thermal windows. Just like in a residential home, dual-pane windows drastically reduce heat transfer and eliminate the severe condensation and frost buildup that plagues single-pane RV windows in the winter.

Premium All-Weather Brands at Hiemstra Trailer Sales

As London's premier dual-brand dealership, we offer the two most proven cold-weather protection packages in the industry, allowing you to camp with absolute confidence.

Jayco: Climate Shield™ Zero-Degree Protection

Jayco takes cold weather seriously. Their legendary Climate Shield™ package is available on premium lines like the Eagle, North Point, and Pinnacle, as well as robust toy haulers like the Seismic.

• Zero-Degree Tested: Jayco doesn't just guess at their insulation values; they prove it. Models equipped with Climate Shield are tested in a Dometic extreme weather chamber to hold a comfortable interior temperature even when it drops to 0°F (-17°C) outside.

• The Magnum Truss™ Roof: Winter camping means snow. Jayco's Magnum Truss Roof System is tested to withstand a massive 4,500 lbs. of pressure—50 percent more than the competition. This means you never have to worry about the structural integrity of your roof under heavy snowfall.

• PEX Plumbing: Jayco utilizes flexible PEX plumbing lines throughout the coach. PEX can expand and contract without bursting, providing an essential layer of safety if temperatures suddenly plummet.

Grand Design: Weather-Tek™ Insulation

Grand Design has built a massive following among full-timers and snowbirds largely due to their uncompromised Weather-Tek™ construction, found on the Reflection, Solitude, and Momentum lines.

• Industry-Leading R-Values: Grand Design packs their luxury units with incredible insulation, achieving equivalents of R-40 in the roof, R-45 in the floor, and R-11 in the sidewalls and slide rooms.

• Attic Ventilation: A major issue with winter camping is condensation building up in the roof space. Grand Design engineers their Weather-Tek package with dedicated attic vents to allow moisture to escape, preventing unseen mold and rot.

• Enclosed Utility Centers: The water hookups are often the first thing to freeze on an RV. Grand Design completely encloses their all-in-one utility centers and actively heats them, keeping your water pump and hookups safe from the elements.

Four-Season Camping Beyond the Winter

Remember, the heavy insulation that keeps you warm in December works just as hard to keep you cool in July! A four-season RV requires significantly less energy to air condition during a brutal summer heatwave. When paired with high-efficiency cooling systems—like Jayco's Whisper Quiet dual A/Cs or Grand Design's Stealth A/C system—a winter-ready RV is truly the most comfortable coach you can own year-round.
