## Overview

The Tiffin Allegro Bay 38 CB is built around a Freightliner S2RV chassis with a Cummins B6.7 360 HP diesel and Allison 3000 MH 6-speed transmission, giving it a serious powertrain for a Class C. Inside, Tiffin leans into a house-like feel with the Spyder Controls multiplex system driving multiple color touchscreens throughout the coach, a 2,000-watt pure sine wave inverter, and dual 15,000-BTU heat pump air conditioners. The over-cab bunk adds sleeping flexibility, and the full composite sidewalls with gel-coat front and rear caps reflect the kind of construction quality Tiffin owners consistently point to. Optional upgrades like lithium house batteries, a 600-watt solar package, and in-motion satellite make the Allegro Bay 38 CB easy to configure for extended off-grid travel.
