All-Weather Polar Pack — Built for True Canadian Camping - The 2026 Alpine Avalanche Edition is fully equipped with Keystone’s tested and proven Polar Pack, delivering genuine four-season capability built for real Canadian conditions. This is more than “extended season”—it’s engineered for year-round Canadian camping, from -30° nights to shoulder-season storms. The Polar Pack adds a heated and enclosed underbelly, Astro-Foil reflective insulation across the roof and end walls, a powerful 35,000 BTU furnace, Darco-wrapped insulated flooring, and static attic vents to maintain thermal balance. Every rotocast holding tank is heated with forced ducted air and protected by 12V heat pads (including two on the oversized 75-gallon fresh tank). All PEX water lines run through heated spaces, and the holding tank pulls are heated as well—giving you the confidence to camp, travel, and live in any Canadian season. Snowbirds, full-timers, mountain campers—this package is built for you.
Where Luxury, Innovation, and Adventure Collide. Your next chapter starts in the Alpine Avalanche 390DS — built for those who expect everything from their RV.
