## Overview

That rear bunkhouse with triple bunks is the centerpiece here — paired with a front King bed suite, you've got genuine sleeping separation between adults and kids rather than just curtains and wishful thinking. The walk-thru bath does double duty between the bedroom and main living space, and a second half bath near the bunk room means mornings don't turn into a traffic jam. Mid-kitchen placement keeps the cook in the middle of everything, with an island for prep space and a second entry door nearby — handy when everyone's tracking in from outside. The outdoor kitchen and entertainment setup extend that living space further, and the Polar Pack makes this more than a fair-weather rig.
