## Overview

Owners call it the number one product on the market, and it's easy to see why. The 4118 pairs a rear King bed and stacked Splendide® washer/dryer with a midship bath featuring a 44" x 30" skylit shower, all wrapped in Newmar's signature full-paint Masterpiece finish with clearcoat and cut and buff. Up front, the cockpit leans hard into technology: Industry-First Comfort Drive™ adaptive steering gives it a remarkably tight feel for a coach this size, backed by OnGuard™ collision mitigation, Mobileye® lane tracking, and dual wireless charging mats. The galley doesn't hold back either. Induction cooktop, convection microwave, solid-surface countertops, and a dedicated pantry with a pot-and-pan drawer make this feel more like a high-end apartment than a motorhome. An exterior entertainment center with Bose® soundbar, perimeter RGB LEDs, and a Dometic® freezer on a pullout tray round out a coach built to be lived in, not just driven.
