## Overview

The Keystone Cougar 357UMR stands out for its rear mudroom layout, which keeps the main living space cleaner and gives pet owners and outdoor enthusiasts a dedicated place to transition in and out of camp. Up front, a King bed anchors the private bedroom, while the kitchen island adds real prep space in the middle of the rig. Two entry doors mean you're not routing traffic through the living area every time someone heads outside. Keystone loads the 357UMR with practical standards like the Ground Control 3.0 auto-leveling system, an 81-gallon freshwater tank, washer/dryer prep in the front wardrobe, and Road Armor suspension to smooth out the miles between destinations.
