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.
