## Overview

The side patio is the headline here — it transforms this toy hauler into something closer to a campsite than a trailer, giving you outdoor living space without sacrificing the garage. Inside, the raised kitchen feels genuinely residential, with premium appliances and enough counter space to actually cook. The bath and a half setup is a practical win for groups sharing the rig, and the heated underbelly makes four-season camping a real option rather than a marketing claim. Build quality has been inconsistent across units, so a thorough PDI and early attention to seals and slides goes a long way with this one.

## We like

- Residential-style kitchen
- Division of space
- Side patio

## Things to consider
