2007 KZJag 28JF2S

KZ lists the 2007 Jag 28JF2S at 7,390 lb dry, a GVWR of 10,000 lb, a net carrying capacity of 2,610 lb and a pin weight of 1,600 lb. Its dry weight plus its carrying capacity comes to exactly its GVWR.

It is 29'8" long and 149" high. KZ prints its tanks as 55 gal fresh, 50 gal grey, 50 gal black.

Among the 19 Jag floorplans KZ’s Jag brochure (filed in KZ’s 2007 brochure folder; the brochure prints no year) lists with a published dry weight, it is number 17 from the lightest, in a range from 3,840 lb (Jag 20J) to 8,724 lb (Jag 38J2S). Every figure in that comparison is KZ’s, for the same model year.

Every number on this page was read on 5 Nov 2026 from KZ’s Jag brochure (filed in KZ’s 2007 brochure folder; the brochure prints no year); model year 2007 comes from where the maker files it on its own site, not from the document’s text.

How the 28JF2S differs from the other three Jag fifth wheels. Most distinctive first. How these ranks are worked out.

• Dry weight, 7,390 lb: heaviest of four; next is the 28JFSS (7,140 lb).
• Pin weight, 1,600 lb: heaviest of four; next is the 28JFSS (1,480 lb).
• Pin weight as a share of dry weight, 21.7%: largest of four; next is the 28JFSS (20.7%).
• Cargo capacity, 2,610 lb: second-smallest of four, between the 23JFS (1,776 lb) and the 28JFSS (2,860 lb).
• Cargo capacity as a share of GVWR, 26.1%: second-smallest of four, between the 23JFS (25.4%) and the 28JFSS (28.6%).
• Length, 29 ft 8 in: longest of four, level with the 28JFSS; next is the 25JFS (26 ft).
• Exterior height, 12 ft 5 in: tallest of four, level with the 28JFSS; next is the 25JFS (11 ft 5 in).

Next to the 28JFSS, the nearest lighter floorplan by dry weight, the 28JF2S is 250 lb heavier by dry weight, has 250 lb less cargo capacity and has a pin weight 120 lb heavier; the two publish the same GVWR, length, exterior height, interior height, fresh tank, grey tank and black tank.

KZ’s Jag brochure (filed in KZ’s 2007 brochure folder; the brochure prints no year) lists 19 Jag floorplans; every one with a printed weight has a page here.

A full 55-gallon fresh tank is about 457 lb of water (water counts as cargo: 49 CFR 571.110 S9.3.2), 17% of the Jag 28JF2S’s 2,610 lb cargo capacity, leaving 2,154 lb. Across 4 Jag fifth-wheel floorplans the water share runs 12% to 17%, and this plan’s is the highest. Nearest on that share: Jag 28JFSS at 16%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.110 S9.3.3).

The record at the top of this page is the 28JF2S from 2007. The maker’s own documents for earlier model years also list the 28JF2S, and that year is printed here: 2006. The figures change from year to year, so check the year on the trailer’s own label. A field a year’s brochure does not print reads “Not published” and is never filled from another year.
