## Overview

The 373RD flips the typical fifth wheel layout by pushing the living area to the rear, which means big windows, a more social atmosphere, and genuine separation between the bedroom and everything else. Up front, the King bed and dual vanity make the bedroom feel like an actual retreat rather than an afterthought. Back in the living space, Thomas Payne electric reclining theater seats and a 5K BTU fireplace set a tone that's hard to argue with after a long driving day. Underneath, the MORryde CRE3000 suspension with Dexter Gladiator axles handles rough roads quietly — something owners consistently call out — while the oversized pass-through storage and rear slide-out tray keep the gear-hauling side of RV life well organized.
