## Overview

The rear kitchen with its own dedicated entry door is a genuinely clever setup — you can haul in groceries or come in from the grill without tracking through the living room. Up front, the full bath with dual vanity sits conveniently near the King bed and walk-in closet, making the bedroom end feel more like a real master suite than an afterthought. The 100" wide-body construction shows throughout, with 6'10" interior height in the slide-outs, a 40" electric fireplace, and Thomas Payne theater seating with built-in heat and USB charging. The heated and enclosed underbelly, hydraulic leveling system, and residential fridge make this one equally at home on a weekend trip or a longer stay.

## We like

- Kitchen entry door
- Large living area

## Things to consider

- Limited counter space
- Limited nightstands
