Beautiful, luxurious. Tiffin Allegro Bus, Beautiful with all the bells and whistles! Full Body Paint, heated floors, stored inside,
The 2018 Tiffin Allegro Bus 45OPP represents the pinnacle of Tiffin's luxury diesel pusher lineup and was engineered for buyers who refuse to compromise on comfort, craftsmanship, technology, and long-distance touring capability.
Built on Tiffin's premium PowerGlide chassis and powered by the proven Cummins ISL9 8.9-liter turbo diesel engine producing 450 horsepower and 1,250 lb-ft of torque, this coach delivers smooth, confident performance whether cruising the interstate, navigating mountain grades, or towing a vehicle behind.
At 45 feet in length with four slide rooms, the 45OPP floorplan was designed to create a true residential living environment. When the slides are extended, the interior opens into an expansive luxury living space featuring premium hardwood cabinetry, polished porcelain tile flooring, solid-surface countertops, designer furnishings, and the meticulous fit and finish that helped establish Tiffin as one of the most respected names in the luxury motorhome industry.
The 45OPP's bath-and-a-half floor plan remains one of the most sought-after layouts ever offered by Tiffin. Guests enjoy convenient access to a mid-coach half bath while owners benefit from a spacious rear master bathroom that provides residential comfort and privacy. The master suite features abundant wardrobe storage, washer and dryer accommodations, premium cabinetry, and a king-size bed, creating a true home-away-from-home experience for extended travel or full-time living.
The gourmet kitchen was designed with full-time travelers in mind and includes a residential refrigerator, induction cooktop, convection microwave, dishwasher, extensive solid-surface counter space, and abundant pantry storage. Whether preparing a quick meal or entertaining guests, the kitchen provides the convenience and functionality expected from a luxury residential environment.
Comfort is exceptional in every season thanks to Tiffin's Aqua-Hot hydronic heating system, heated tile flooring, and three roof-mounted 15,000 BTU air conditioning units providing approximately 45,000 BTU of cooling capacity. The result is consistent climate control and residential comfort regardless of outside temperatures.
Technology throughout the coach was designed to simplify ownership and enhance the travel experience. The Spyder multiplex control system allows centralized management of lighting, climate control, slide rooms, awnings, generator functions, and numerous coach systems through integrated touchscreen controls. Premium entertainment systems, multiple televisions, advanced electronics, and luxury appointments throughout the coach create an environment that rivals that of many upscale homes.
Outside, the Allegro Bus showcases full-body paint, flush-mounted slide rooms, power patio awnings, exceptional basement storage capacity, premium exterior lighting, and a robust tag-axle chassis designed for superior ride quality and stability. The PowerGlide chassis, independent front suspension, and air-ride system combine to provide the smooth handling characteristics that have made the Allegro Bus one of the most respected luxury coaches on the road.
The Allegro Bus has long been considered one of the benchmark luxury diesel pushers in North America. Combining exceptional build quality, luxury residential amenities, advanced technology, and renowned Tiffin craftsmanship, the 45OPP was designed to deliver a first-class travel experience for owners seeking the very best in diesel motorhome luxury.

Condition:
This 2018 Tiffin Allegro Bus has been owned by the original owner since new and appears to have been well cared for throughout its ownership. The coach has spent the majority of its life stored indoors in South Carolina and has been kept covered when not in the garage since the owner's relocation. The owner reports the coach has never been smoked in and has only been occupied by two small dogs.
According to the owner, major preventive maintenance was completed in December 2025, including servicing the engine, transmission, generator, and Aqua-Hot system. The roof was also inspected and resealed around the skylights during that service period. Maintenance records indicate the coach has received regular care and attention throughout ownership.
The house battery bank was replaced within the last six months. The chassis batteries are reported to be original. Tire age is mixed, with the front and tag axle tires having been replaced previously. The drive axle tires remain dated 2017 and have not yet been replaced. The owner had planned to replace them, but has not done so.
Overall, the interior and exterior of the coach present well for its age. A small tear is present in the sofa upholstery. The owner also reports a cracked frame or bezel on the passenger-side control module. These items are considered minor cosmetic defects.
A functional issue exists with the driver's navigation touchscreen. The owner reports that the original navigation and radio system was replaced in December 2025 after support for the factory system was discontinued. Following the update, navigation functions remain operational; however, the driver's touchscreen no longer functions as intended. Navigation controls are currently accessed through the passenger-side module.
Based on the owner's representations, the coach appears to be in good overall condition with recent major services completed and a history of indoor storage. Known deficiencies include the inoperative driver's navigation touchscreen, aged drive axle tires that should be considered for replacement, the original chassis batteries, the cracked passenger-side module frame, and the minor tear in the sofa upholstery. Aside from these noted items, the owner reports that the major systems are functioning properly.
As with any pre-owned motorhome, buyers are encouraged to conduct their own due diligence and obtain a professional third-party inspection to verify the condition and operation of all systems.
