2017 KZSpree S312BHK

KZ lists the 2017 Spree S312BHK at 7,150 lb dry, a GVWR of 8,300 lb, a net carrying capacity of 1,150 lb and a tongue weight of 720 lb. Its dry weight plus its carrying capacity comes to exactly its GVWR.

It is 35' 6" long and 11' 2" high. KZ prints its tanks as 40 gal fresh, 32 gal grey, 32 gal black.

Among the 10 Spree floorplans KZ’s Spree brochure (filed in KZ’s 2017 brochure folder; the brochure prints no year) lists with a published dry weight, it is number 4 from the lightest, in a range from 5,590 lb (Spree S261RK) to 8,420 lb (Spree S323RK). 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 Spree brochure (filed in KZ’s 2017 brochure folder; the brochure prints no year); model year 2017 comes from where the maker files it on its own site, not from the document’s text.

KZ’s Spree brochure (filed in KZ’s 2017 brochure folder; the brochure prints no year) lists 10 Spree floorplans; every one with a printed weight has a page here.

A full 40-gallon fresh tank is about 332 lb of water (water counts as cargo: 49 CFR 571.110 S9.3.2), 29% of the Spree S312BHK’s 1,150 lb cargo capacity, leaving 818 lb. Across 10 Spree floorplans the water share runs 22% to 33%, and 4 give up more than this one. Nearest on that share: Spree S261RK at 27% and Spree S261RKC at 30%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.110 S9.3.3).
