2026 GRAND DESIGN LINEAGE SERIES M 25TK
Description
The Grand Design Lineage 25TK sets a new benchmark in compact luxury motorhomes. Built on a Mercedes-Benz Sprinter 4500 chassis with a MORryde Halo frame for enhanced stability, it delivers performance and refinement in a nimble 25' 8" package. Powered by a twin-turbo 2.0 L inline-4 diesel (208 hp, 332 lb-ft) and paired with a 9G-Tronic 9-speed automatic, this coach offers both driveability and power.
Inside, the flexible sleeping layout features twin power-adjustable 36″ × 80″ and 36″ × 74″ beds that convert into a king-sized bed (70″ × 80″), complete with headboard controls, USB ports, and storage. The bathroom pioneers an AquaHaven “walk-through” wet-dry design that can be used as a rain shower or enclosed dry bath—luxuriously tiled and heated for year-round comfort.
Premium touches abound: a 10 cu ft 12 V refrigerator, tankless water heater, SharkBite plumbing, integrated Starlink internet, Rockford Fosgate audio, Firefly Power system with lithium batteries, and a powerful 4.5 kW generator.
Compact yet commanding, the Lineage 25TK blends high-end construction, innovative design, and smart living—perfect for modern travelers seeking luxury in a maneuverable Class C coach.
