The 2026 Grand Design Lineage Series M 25FW raises the bar for Class C RVs — blending luxury, confidence, and adventure into one bold coach. From a true king bed and smart interior storage to a modern kitchen, flexible sleeping space, and a smooth ride on the Mercedes-Benz Sprinter 4500 chassis, this coach proves that luxury and adventure can live in the same place. 👉 See it. Feel it. Drive it — at La Mesa RV. #granddesign #classc #rvliving #2026rv #rving
