Angie Morell, RV Expert Angie from NIRVC, introduces you to the all-new Class A Diesel 2027 Tiffin Motorhomes Allegro Bus 45OPP.
The 2027 Tiffin Allegro Bus 45 OPP is a flagship Class A diesel pusher built on Tiffin’s premium PowerGlide raised-rail tag axle chassis and powered by a Cummins diesel engine—typically the 450HP L9 standard, with available 605HP X15 upgrade depending on configuration—delivering the power and refinement expected from a top-tier luxury coach. At 45 feet long, the 45 OPP offers an expansive quad-slide floorplan with a bath-and-a-half layout, king bed suite, high-end residential appliances, premium handcrafted cabinetry, heated tile floors, and bus-level luxury throughout. Combining massive towing capability, tag-axle stability, and Tiffin’s renowned fit and finish, the 45 OPP is built for buyers who want uncompromising comfort and performance at the very top of the diesel pusher market.
