The Keystone Avalanche 366LS puts the kitchen at the back where it belongs in a layout this size, opening up the living area and giving the whole rig a roomy, residential feel. The 100" wide body construction and 6'10" tall summit slides make a real difference day-to-day, and details like a Girard on-demand tankless water heater, solid surface countertops, and a Furrion refrigerator with ice maker push it firmly into the full-timer category. A King bed, dual Coleman-Mach 15K BTU air conditioners, and the Polar Pack four-season climate package mean the Avalanche 366LS is set up for comfort in more than just mild weather. The Lippert Titan hydraulic auto-leveling system with its digital touchscreen takes the headache out of setup, and stackable washer and dryer prep keeps long-term convenience on the table.
