## Overview

The 346FL flips the traditional layout by putting the living room up front, which means massive windows, a social hub away from the sleeping area, and a sofa that converts to a Queen bed for extra guests. Out back, the King bed bedroom has its own rear-entry door — a small detail that makes a big difference when you're loading up for a long trip. Keystone built this one to handle real conditions: Subzero-rated "Polar Packed" insulation, three AC units, double-welded aluminum frames, and 7,000-pound Dexter axles underneath. Owners consistently rave about the walk-in pantry, the passthrough storage, and a residential Samsung fridge backed by a JBL sound system that makes it feel less like camping and more like relocating your living room.
