## Overview

Three slides open up the 3321MK into something that feels more like a cabin than a trailer, with the mid-kitchen placement keeping cooking and living spaces genuinely separate. Keystone loaded this one with features that typically require stepping up to a heavier, pricier rig. Tankless water heater, washer/dryer prep, and the kind of fit and finish that holds up after a few seasons on the road. The full bath rounds out a floor plan designed for two people who don't want to compromise, with enough sleeping space to bring along guests without crowding the living areas.
