01 What makes it unique
KZ lists the 2017 Spree S323RE at 8,410 lb dry, a GVWR of 9,500 lb, a net carrying capacity of 1,090 lb and a tongue weight of 1,020 lb. Its dry weight plus its carrying capacity comes to exactly its GVWR.
It is 35' 11" long and 11' 6" 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 9 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 S323RE differs from the other nine Spree floorplans. Most distinctive first. How these ranks are worked out.
- Dry weight, 8,410 lb: second-heaviest of ten, between the S333RIK (8,160 lb) and the S323RK (8,420 lb).
- Tongue weight, 1,020 lb: third-heaviest of ten, between the S322RL (970 lb) and the S323RK (1,070 lb).
- Tongue weight as a share of dry weight, 12.1%: fourth-largest of ten, between the S333RLI (11.6%) and the S323RK (12.7%).
- Length, 35 ft 11 in: fifth-longest of ten, between the S312BHK (35 ft 6 in) and the S333RIK (36 ft 2 in).
- Cargo capacity as a share of GVWR, 11.5%: shared with the S303RL; of nine, one smaller and six larger, nearest the S323RK (11.4%) and the S312BHK (13.9%).
- Cargo capacity, 1,090 lb: shared with the S261RKC; of ten, two smaller and six larger, nearest the S323RK (1,080 lb) and the S312BHK (1,150 lb).
- Exterior height, 11 ft 6 in: tallest of ten, level with the S323RK, S333BHK and S333RIK; next is the S333RLI (11 ft 3 in).
- GVWR, 9,500 lb: highest of ten, level with the S323RK, S333BHK and two others; next is the S303RL (8,800 lb).
Next to the S333RIK, the nearest lighter floorplan by dry weight, the S323RE is 250 lb heavier by dry weight, has 250 lb less cargo capacity, has a tongue weight 280 lb heavier and is 3 in shorter; the two publish the same GVWR, exterior height, interior height, fresh tank, grey tank and black tank.
Next to the S323RK, the nearest heavier floorplan by dry weight, the S323RE is 10 lb lighter by dry weight, has 10 lb more cargo capacity, has a tongue weight 50 lb lighter, is 1 ft 5 in shorter and has a grey tank 32 gal smaller; the two publish the same GVWR, exterior height, interior height, fresh tank and black tank.

Towing it
Check your vehicle. Enter the ratings from your owner’s manual and the door-pillar placard.
Compares your figures with this page’s published GVWR (9,500 lb) and the upper loaded tongue estimate (1,425 lb, a rule of thumb). Your vehicle’s placard and the trailer’s own weight label govern.
Loaded range: 10–15% of GVWR on the tongue, a rule of thumb, not a measurement of this unit. No truck ratings or hitch classes (why; NHTSA, DOT HS 809 433). The range starts at the published figure, because loaded is never lighter than that.

04 Notes on this floorplan
What KZ does not publish for the Spree S323RE
KZ prints no sleeping capacity for this model, so none is given. Nothing is filled from a sibling model, a different model year or a dealer listing.
Read the label on the trailer
Federal rules put a load-carrying label inside every RV trailer: its unloaded weight with full propane, its cargo carrying capacity and its GVWR (49 CFR 571.110 and 571.120). Those figures come from the trailer itself and govern the towing decision.
05 How it compares
8,160 lb dry and 9,500 lb GVWR, against this model’s 8,410 lb and 9,500 lb.
8,420 lb dry and 9,500 lb GVWR, against this model’s 8,410 lb and 9,500 lb.
06 Loading it for a trip
A full 40-gallon fresh tank is about 332 lb of water (water counts as cargo: 49 CFR 571.110 S9.3.2), 30% of the Spree S323RE’s 1,090 lb cargo capacity, leaving 758 lb. Across 10 Spree floorplans the water share runs 22% to 33%, and 2 give up more than this one. Nearest on that share: Spree S261RKC at 30% and Spree S323RK at 31%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.110 S9.3.3).
07 Where this floorplan sits
Closest sibling: the Spree S303RL, nearest on the published figures. It differs on 5 of the 8 fields both publish (this plan first): length 35 ft 11 in vs 34 ft 6 in; dry weight 8,410 lb vs 7,790 lb; GVWR 9,500 lb vs 8,800 lb; cargo capacity 1,090 lb vs 1,010 lb; hitch weight 1,020 lb vs 1,170 lb. They match on fresh tank, grey tank and black tank.

09 What this page publishes, and what it does not
12 of the 18 fields this catalogue tracks are published for the Spree S323RE. Not published: sleeps, slide count, axle count, refrigerator, air conditioning, tire size (a description is published, a size is not).

10 Manuals & documents
Sources: kz-rv.com (linked below); the full source note is at the foot of the page.
11 NHTSA safety record
NHTSA holds 7 recall campaigns and 6 owner complaints (model years 2005 on) against the Spree line (a recall and a complaint are not the same thing).
Too few reports to show a pattern. 6 complaints have been filed on this line — not enough to say what fails most often. They cover electrical system, equipment, service brakes, structure, trailer hitches and wheels.
Recall coverage here is not complete, and complaints are owners’ unverified reports (how this record is built). Check a specific VIN at NHTSA before you buy. Full tables are on the Spree line page.
Owner’s manuals
The maker’s own owner’s manual for each model year on this page, linked where the maker publishes it. Each link goes to the maker’s file, labelled as the maker labels it; a year with no manual of its own is not filled from another year.
