2026 Grand Design Lineage Series M 25TK

2026 Grand Design Lineage 25TK Series M Class C Motorhome highlights: • Mercedes-Benz Sprinter 4500 Cab Chassis • 25’ 8 “ Long • Dual Power Seating Living • Cab Over Bunk • Rear Dual Twin to King Tilt-a-Bed • 16” Awning • 40” Exterior TV When you walk up to the 2026 Grand Design Lineage Series M 25TK, you’ll immediately see this is a whole different level of motorized luxury. Built on the Mercedes-Benz Sprinter 4500 cab chassis, this rig gives you 208 horsepower and 332 lb-ft of torque from the twin-turbo 2.0L inline-4 paired with a 9G-Tronic automatic, letting you drive with confidence and refined smoothness. Slide in at the driver’s seat and you’re sitting in a true cockpit experience: heated and power-adjusted seats with lumbar support, leather-wrapped steering wheel, and the MBUX infotainment system including Apple CarPlay/Android Auto. Then step into the living area, and you realize this isn’t just a “drive” rig; Grand Design has put the build quality of their high-end towables into this motorhome. The exterior is finished with heavy-gauge aluminum framing laminated with block-foam insulation, Azdel OnBoard composite sidewalls, dual-pane windows, and a one-piece fiberglass roof with Titan Gasket seal system, all designed for durability, comfort, and quiet travel. Inside, the 25TK has a layout that emphasizes usable space and premium finishes. The living room features theater seating (or an optional dinette) with built-in USB/USB-C charging, and a 32″ LED smart TV. The kitchen steps up with a 10 cu. ft. 12-volt 3-door refrigerator, a 2-burner stove with glass cover, matte-black pull-out kitchen faucet, solid-surface countertops with flip-up extension, and a full-sized stainless sink. In the rear, you have a twin to king tilt-a-bed, under-bed storage, its own 32″ smart TV, and USB ports. This gives you versatility in the main sleeping cabin and real comfort for extended travel. The bathroom is equally refined: custom shower surround with linear-slot drains and SeaDek pad, matte-black hardware, porcelain toilet, and power vent. This is a motorhome where you do not compromise. When it comes to power & utilities, the 25TK offers a 4.5 kW generator with auto-start, Titan aluminum 4-point hydraulic leveling jacks, lithium coach batteries, 540 watts of solar power, and a full “smart-home” style command center. From driving to living, this motorhome is built to travel far, stay comfortable, and endure the rigors of real life on the road. At Clear Creek RVs, this is the type of unit we point to when someone wants a “step up” in the driving-and-living experience.
