What changed this year
Tiffin's 'What's New for 2025 Models' post (March 2024) says two roof awnings, heated tile floors, a dishwasher, power window awnings, a washer and dryer, a basement freezer, a power king bed and Starlink became standard, with new paint schemes and a redesigned pull-out island.
Notes
Length, chassis and slide-out count vary by floorplan; see the floorplan records. This revision of the sheet (dated 2.7.25) lists only the Cummins L9 and no 605-horsepower option. DEF tank 10 gallons. The sheet does not print a model year on the page; the year comes from its file name and Tiffin's library label. The product brochure linked here was not opened.
