## Overview

The rear kitchen anchors this thoughtfully designed layout, flowing seamlessly into a mid-bunk room and spacious master bedroom that owners consistently praise for its smart use of space. One long-term owner lived in their 3400SB for three months during a job transfer and still raves about the experience nine years later. The combination of separated sleeping areas and well-planned common spaces makes this floor plan particularly livable for families or anyone planning extended adventures.
