A luxury diesel pusher with confident road manners, the Tiffin Allegro Bus 40 SP pairs a Cummins ISL9 engine and Allison six-speed transmission with independent front suspension and an engine brake. Inside, the driver benefits from navigation, side-view cameras, power shades, and a wraparound dash, while the living space includes a front overhead TV and one full bath. Full-body paint, an exterior TV, automatic awnings, heated storage compartments, and pass-through basement storage extend the coach’s upscale feel outdoors.
