The Chinook Summit SS 360 is a premium adventure van designed for travelers who want luxury, capability, and off-grid freedom in a compact footprint. Built on the Mercedes-Benz Sprinter AWD chassis, this coach combines upscale craftsmanship with impressive touring capability. Inside, the innovative lounge design features opposing sofas that create a comfortable seating area during the day and quickly convert into a spacious 76" x 84" sleeping area at night. Large side windows, premium cabinetry, overhead storage, and a front entertainment center with TV create a bright and inviting atmosphere throughout the coach.
The galley kitchen is thoughtfully arranged with solid-surface countertops, an induction cooktop, convection microwave, stainless sink, and a 12V refrigerator, making meal preparation simple whether you're parked at a campground or boondocking off the grid. At the rear, a fully equipped wet bath provides the convenience of a private shower and toilet without sacrificing valuable living space. Advanced off-grid features including a 600-watt solar system, large lithium battery bank, hydronic heating system, tankless hot water, and a powerful inverter allow you to travel comfortably for extended periods without hookups.
Outside, the sleek Chinook body design, expansive storage compartments, and power awning make every campsite more enjoyable. Combining luxury accommodations, advanced technology, and exceptional off-grid capability, the Summit SS 360 is an outstanding choice for couples seeking a versatile Class B+ motorhome ready for everything from cross-country road trips to remote outdoor adventures.
The Summit is Four-Seasons Certified, featuring insulated construction and premium systems designed to help you travel comfortably in a wide range of climates throughout the year.
And the insulation works in both directions: the construction that helps retain warmth in cold conditions also helps reduce heat transfer from outside during hot weather, supporting a more comfortable interior across changing climates.
Feature details are from the 2026 model year.
