2007 KZJag 38J2S

KZ lists the 2007 Jag 38J2S at 8,724 lb dry, a GVWR of 10,000 lb, a net carrying capacity of 1,670 lb and a tongue weight of 1,100 lb. KZ’s own figures do not add up — a conflict, stated not resolved: 8,724 lb dry plus 1,670 lb carrying capacity is 10,394 lb, against a printed GVWR of 10,000 lb. All three are shown as KZ prints them and none is corrected; the federal label on the trailer is the one to trust.

It is 38'8" long and 131" high. KZ prints its tanks as 30 gal fresh, 35 gal grey, 35 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 19 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 38J2S differs from the other fourteen Jag travel trailers. Most distinctive first. How these ranks are worked out.

• Dry weight, 8,724 lb: heaviest of fifteen; next is the 38JSS (7,780 lb).
• Cargo capacity, 1,670 lb: second-smallest of fifteen, between the 29JBS (1,380 lb) and the 26JS (2,130 lb).
• Tongue weight, 1,100 lb: second-heaviest of fifteen, between the 33J2S (798 lb) and the 29JSS (1,110 lb).
• Tongue weight as a share of dry weight, 12.6%: fifth-largest of fifteen, between the 21JQ (11.9%) and the 28JBSS (12.7%).
• Length, 38 ft 8 in: longest of fifteen, level with the 38JSS; next is the 33J2S (34 ft 2 in).
• GVWR, 10,000 lb: highest of fifteen, level with the 28JBSS, 28JSS and four others; next are the 25JQ, 25JS and three others (7,000 lb).

Next to the 38JSS, the nearest lighter floorplan by dry weight, the 38J2S is 944 lb heavier by dry weight, has 550 lb less cargo capacity and has a tongue weight 400 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 30-gallon fresh tank is about 249 lb of water (water counts as cargo: 49 CFR 571.110 S9.3.2), 15% of the Jag 38J2S’s 1,670 lb cargo capacity, leaving 1,421 lb. Across 15 Jag travel-trailer floorplans the water share runs 6% to 18%, and 1 gives up more than this one. Nearest on that share: Jag 26JS at 12% and Jag 29JBS at 18%. 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 38J2S from 2007. The maker’s own documents for earlier model years also list the 38J2S, 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.
