Class b motorhomes that share features with the Summit SS, like rear bath and rear facing entry door.
The Chinook Summit SS is built around a Mercedes-Benz Sprinter with AWD and a twin-turbo diesel engine, so it goes places most Class B motorhomes won't follow. The off-grid credentials are equally serious: a 900 amp-hour Expion 360 lithium battery bank, a 600-watt solar system with four additional plug-in ports for up to 480 more watts, and a Victron 3000-watt inverter handle the power side, while the Timberline diesel hydronic system covers heat and on-demand hot water without a generator in sight. Inside, the front living layout keeps things comfortable with a sofa that converts to a bed, solid surface countertops, a porcelain toilet, and a full bath, and Starlink Standard keeps you connected wherever the AWD chassis takes you. Owners consistently call the Chinook Summit SS well thought out and surprisingly spacious, with a luxury feel that doesn't come at the cost of driveability.
