Floorplans offered in 2025
45 FZ45 PZ
What changed this year
Tiffin's 'What's New for 2025 Models' post (March 2024) lists Starlink Pro as standard, matte tile floor options, a grey tank flush, hot and cold water at the front cap, new paint schemes and a redesigned pull-out kitchen island. The 45 PZ floorplan joins the 45 FZ; the 2024 brochure lists only the 45 FZ.
Notes
The sheet lists three slide-outs for each floorplan; Tiffin's 2027 model page describes the 45 PZ as a quad-slide, so treat the 45 PZ count with care. Wheelbase 316 in, GVWR 54,000 lb, GCWR 74,000 lb, hitch rating 20,000 lb, tag axle 13,000 lb, DEF tank 15 gallons. The document's embedded title is 'MY25 Zephyr Specifications_10.28.24'. The product brochure linked here was not opened.
