Make room for more comfort, performance, and longer stays in an Allegro Bay Super C diesel coach by Tiffin Motorhomes.

Each Allegro Bay is dry camp ready thanks to the 150-gallon fresh water tank, and you'll enjoy more power provided by the AGM extended cycle house batteries, or the optional Lithium Ion house batteries. Handcrafted cabinetry will add to the luxury you'll find throughout the Allegro Bay, and the Spyder Multiplex system with app compatibility puts you in control of all your coach's functions.
