## Overview

What sets the 351BH apart is the fully separate rear bunkhouse, which keeps the kids' space genuinely private rather than just curtained off from the main living area. Up front, the bedroom runs east/west with a King bed, while the kitchen island, booth dinette, and 5K BTU fireplace make the main living space feel more like a cabin than a trailer. The outdoor kitchen is a real one. Not just a pass-through shelf, and the MORryde suspension package with CRE3000 and Dexter Gladiator axles means this 39-footer actually tows like something shorter. Keystone backs the structure with a 3-year limited warranty, and features like the Ground Control 6-point auto-leveling with hitch memory take a lot of the setup hassle out of long trips.
