There's a reason owners describe the Allegro Bus 45 BTP as one of the easiest-driving big diesel pushers on the road. It runs on a Cummins L9 450 HP engine paired with ZF independent front suspension, a steerable tag axle, and custom-tuned Koni shocks, so the ride stays smooth even at 45 feet. Bob Tiffin's limited-edition treatment brings serious tech throughout, including the Spyder Controls multiplex system with touchscreens at nearly every station, an Aqua-Hot 450D hydronic heating setup, and a full suite of safety gear like adaptive cruise, collision mitigation, and electronic stability control. With optional lithium batteries, up to six 200-watt solar panels, and powered slide-out storage trays, this is a coach built for serious full-time travel.
