2017 KZSpree S303RL

KZ lists the 2017 Spree S303RL at 7,790 lb dry, a GVWR of 8,800 lb, a net carrying capacity of 1,010 lb and a tongue weight of 1,170 lb. Its dry weight plus its carrying capacity comes to exactly its GVWR.

It is 34' 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 6 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.

How the S303RL differs from the other nine Spree floorplans. Most distinctive first. How these ranks are worked out.

• Tongue weight, 1,170 lb: heaviest of ten; next is the S323RK (1,070 lb).
• Tongue weight as a share of dry weight, 15%: largest of ten; next is the S322RL (13.9%).
• Length, 34 ft 6 in: third-shortest of ten, between the S261RK and S261RKC (28 ft 9 in) and the S322RL (35 ft 1 in).
• Dry weight, 7,790 lb: fifth-heaviest of ten, between the S333RLI (7,770 lb) and the S333BHK (8,130 lb).
• GVWR, 8,800 lb: fifth-lowest of ten, between the S312BHK and S322RL (8,300 lb) and the S323RE, S323RK and three others (9,500 lb).
• Cargo capacity as a share of GVWR, 11.5%: shared with the S323RE; of nine, one smaller and six larger, nearest the S323RK (11.4%) and the S312BHK (13.9%).
• Exterior height, 11 ft 2 in: shared with the S312BHK and S322RL; of ten, two lower and five taller, nearest the S261RK and S261RKC (11 ft 1 in) and the S333RLI (11 ft 3 in).

Next to the S333RLI, the nearest lighter floorplan by dry weight, the S303RL is 20 lb heavier by dry weight, has a GVWR 700 lb lower, has 520 lb less cargo capacity, has a tongue weight 270 lb heavier, is 1 ft 11 in shorter and stands 1 in lower; the two publish the same interior height, fresh tank, grey tank and black tank.

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), 33% of the Spree S303RL’s 1,010 lb cargo capacity, leaving 678 lb. Across 10 Spree floorplans the water share runs 22% to 33%, and this plan’s is the highest. Nearest on that share: Spree S323RK at 31%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.110 S9.3.3).
