From Tiffin Motors:

Make room for more comfort, performance, and longer stays in an Allegro Bay Super C diesel coach by Tiffin Motorhomes. The Freightliner custom chassis features a full-time NoSPIN differential single rear axle so you can navigate tougher terrain, and the 12,000 lb. towing capacity means larger cargo can come along! 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. An all-electric option is also available on this coach and features an AquHot ultra compact hydronic heating system and an induction cooktop, removing the need for a propane tank. Adventure is just a step away with the Allegro Bay Super C diesel coach by Tiffin Motorhomes.
