Looking to buy a 2026 Grand Design Lineage Series M Class C RV?

Compact Class C diesel on a powerful Ford chassis
Front living layout — great open flow and space utilization
Comfortable rear bedroom with real privacy
Well-laid-out kitchen with solid counter space and storage
Practical bathroom with usable shower and real space
Easy-to-drive size with big-coach feel inside
Built solid for road trips, weekend getaways, or full-time travel

The 2026 Grand Design Lineage 25FW is one of those motorhomes that feels right the moment you step in. It’s a manageable size — easy enough to drive and park — but inside it doesn’t feel tiny. The front living layout gives you a great open feel when you walk through the door, and the way the space flows makes it feel bigger than the numbers on paper.

Up front, the living area is comfortable and laid out so you actually want to relax there — not just use it as a pass-through. The kitchen gives you real prep space and storage that makes cooking on the road feel natural instead of cramped. The bedroom in the back gives you real privacy and a comfortable place to crash, and the bathroom has a shower you can stand in instead of a “shower stall.”

One of the best things about this coach is it’s easy to drive — you don’t feel like you’re piloting a bus, but once you’re parked, it still feels like a solid home away from home. That’s exactly what you want in a Class C diesel: manageable on the road, comfortable at camp.

Overall, the Lineage 25FW is practical, comfortable, and easy to live in. It’s a great fit whether you’re doing weekends, week-long trips, or longer travels — all the comfort you need without over-complicating things.
