## Overview

The 31B is built around a clever use of vertical space — bunk beds mid-coach plus a cab-over bunk mean the whole crew is covered without sacrificing a livable common area. A walk-thru bath keeps morning routines moving, and the rear east/west bed with a rear window gives the sleeping area a surprisingly airy feel. On the road, the Ford F53 chassis with its 7.3L V8 and Driver Confidence Package (adaptive cruise, pre-collision assist, lane keeping, and more) handles the driving duties confidently. Owners consistently call out the spacious layout and storage as standout strengths, and options like the powered StudioLoft bed, theater seating, and a full cooling upgrade package give you plenty of room to configure it exactly how you want.
