Is this the BIGGEST RV Living Area? 2026 Keystone Alpine 366LS

Looking for one of the most spacious and luxurious fifth wheels on the market? Meet the 2026 Keystone Alpine Avalanche 366LS, a full-profile fifth wheel with some of the largest interior living space we’ve ever seen.

We first toured this model last year and it’s still one of our absolute favorites. The rear kitchen layout is a showstopper with a roomy island that’s all counter space with no sink in the way, plus tons of storage. The living room is designed for maximum comfort, with a massive L-shaped sofa perfect for you, your guests, and even the dogs. Need more seating? You’ve also got another sleeper sofa and a dedicated desk. Along with the dinette, that means you have two dedicated workspaces, or even three if you count the couch. Perfect for RVers who live and work on the road.

The bathroom features a one-piece shower, and in the bedroom you’ll find washer and dryer prep in its own closet. Whether you’re camping on weekends or living full-time, the 366LS makes it easy and gives you the extra space you’ve been dreaming about.

📌 If you love room to stretch out, functional work areas, and residential comfort in your RV, the Keystone Alpine Avalanche 366LS should definitely be on your list.
