## Overview

This is the kind of fifth wheel owners describe as a "luxury house on wheels," and the mid-bunk layout is what makes the Keystone Avalanche 366MB stand out. You get a genuinely roomy living area, a large residential-style fridge, and a walk-in pantry that make settling in for long stays easy, all warmed up by a fireplace. Owners consistently rate the floorplan and towing manners among the best parts of the Avalanche 366MB, and with room to sleep eight it handles a full crew without feeling cramped.
