What changed this year
The sheet marks the fresh, grey and black water capacities as updated. Against the 2026 sheet, fuel capacity rises from 150 to 175 gallons and the water tanks change from 100/100/55 to 96/91/53 gallons (fresh/grey/black). The sheet lists six 200-watt solar panels as standard, where the 2026 sheet lists solar panels only as options.
Notes
Slide-out count is left blank: the sheet lists three slide-outs for both floorplans, but Tiffin's 2027 Zephyr page describes the 45 PZ as a quad-slide. The sheet names the chassis only as PowerGlide SL; Tiffin's 2025 Zephyr sheet calls it a Freightliner PowerGlide SL. Other figures: wheelbase 316 in, GVWR 54,000 lb, GCWR 74,000 lb, hitch rating 20,000 lb, DEF tank 15 gallons. The sheet does not print a model year; the year comes from its file name and from the 2027 Zephyr page that links to it. The product brochure linked here was too large to open.
