## Overview

Putting the living area at the rear is a smart move in the 355FBS. Those panoramic windows make it feel more like a lounge than a trailer. The bath-and-a-half setup means the front full bath stays clean and accessible without traffic running through the bedroom, and the kitchen island gives you actual prep space rather than a cramped galley. Keystone loads this one with thoughtful details: a pivot hinge entertainment center with a hidden pantry, an electric fireplace with remote, and full pass-through storage with built-in power outlets and TV hookups. The 76-gallon fresh tank and dual-heated holding tanks are a real advantage if you're planning longer stretches away from hookups.
