## Overview

The Allegro Bus 45 OPP is what owners mean when they say an RV feels like a house — heated tile floors, a King bed master suite, and a bath and a half in a rear-bath layout that keeps the living area open and functional. Tiffin's PowerGlide XC chassis with the Cummins L9 450-hp diesel and Reyco Granning air ride rear suspension delivers a genuinely smooth, planted drive that surprises people expecting something this size to feel unwieldy. The Spyder multiplex system puts control of lighting, climate, and systems on touchscreens throughout the coach — including at the entry and exterior — while the Aqua-Hot 450D keeps everything warm without running the generator. Tiffin's steel basement construction means exceptional storage underneath, and the outdoor entertainment setup rounds out a layout that's equally suited to a rally site or a long-term park.
