## Overview

What sets the 338GK apart is its rear living floor plan — the lounge, fireplace, and bar are all tucked at the back, giving the King bed up front its own quiet retreat. The walk-through bath is a smart touch, accessible even with the slides in, and the kitchen peninsula with bar seating makes the interior feel more like a cabin than a trailer. Outside, a full outdoor kitchen extends your living space when the weather cooperates. Practical upgrades like the Girard tankless water heater, dual 15K BTU air conditioners, washer/dryer prep, and the Lippert hydraulic auto-leveling system round out what is genuinely a well-appointed rig for extended stays.
