## Overview

The barreled ceiling is one of those things you notice immediately — it opens up the interior in a way flat ceilings just don't. Heartland built this one with 5/8" plywood floors, Azdel composite walls, and a fully heated underbelly, so it handles shoulder-season trips without complaint. The u-shaped dinette gives you real sit-down space, and owners consistently call out the counter space as unusually generous for the size. It's a layout that reads more like a compact apartment than a travel trailer.
