01 What makes it unique
KZ lists the 2024 Venom V3912TK at 14,620 lb dry, a GVWR of 19,000 lb, a net carrying capacity of 4,380 lb and a pin weight of 3,170 lb. Its dry weight plus its carrying capacity comes to exactly its GVWR.
It is 43' 8" long and 13' 4" high. KZ prints its tanks as 100 gal fresh, 90 gal grey, 50 gal black.
Among the 6 Venom floorplans KZ’s 2024 Venom brochure lists with a published dry weight, it is number 5 from the lightest, in a range from 12,540 lb (Venom V3413TK) to 15,110 lb (Venom V4013TK). 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 2024 Venom brochure, the maker’s own dated document for model year 2024.
How the V3912TK differs from the other five Venom floorplans. Most distinctive first. How these ranks are worked out.
- Dry weight, 14,620 lb: second-heaviest of six, between the V3815TK (13,760 lb) and the V4013TK (15,110 lb).
- Pin weight, 3,170 lb: second-heaviest of six, between the V3916TK (2,840 lb) and the V4013TK (3,340 lb).
- Pin weight as a share of dry weight, 21.7%: second-largest of six, between the V3916TK (21.2%) and the V4013TK (22.1%).
- Cargo capacity, 4,380 lb: third-largest of six, between the V4013TK (3,890 lb) and the V3815TK (5,240 lb).
- Cargo capacity as a share of GVWR, 23.1%: third-largest of six, between the V3413TK (21.6%) and the V3815TK (27.6%).
- Length, 43 ft 8 in: longest of six, level with the V3916TK; next is the V4013TK (43 ft 6 in).
- Grey tank, 90 gal: largest of six, level with the V3916TK and V4013TK; next are the V3313TK, V3413TK and V3815TK (50 gal).
Next to the V3815TK, the nearest lighter floorplan by dry weight, the V3912TK is 860 lb heavier by dry weight, has 860 lb less cargo capacity, has a pin weight 550 lb heavier, is 10 in longer, has a grey tank 40 gal larger and has a black tank 40 gal smaller; the two publish the same GVWR, exterior height, interior height, fresh tank and sleeping capacity.
Next to the V4013TK, the nearest heavier floorplan by dry weight, the V3912TK is 490 lb lighter by dry weight, has 490 lb more cargo capacity, has a pin weight 170 lb lighter and is 2 in longer; the two publish the same GVWR, exterior height, interior height, fresh tank, grey tank, black tank and sleeping capacity.

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 (19,000 lb) and the upper loaded pin estimate (4,750 lb, a rule of thumb). Your vehicle’s placard and the trailer’s own weight label govern.
Loaded range: 15–25% of GVWR on the pin, 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 Venom V3912TK
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
13,760 lb dry and 19,000 lb GVWR, against this model’s 14,620 lb and 19,000 lb.
15,110 lb dry and 19,000 lb GVWR, against this model’s 14,620 lb and 19,000 lb.
06 Loading it for a trip
A full 100-gallon fresh tank is about 830 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 19% of the Venom V3912TK’s 4,380 lb cargo capacity, leaving 3,550 lb (444 lb per rated berth). Across 6 Venom floorplans the water share runs 15% to 26%, and 3 give up more than this one. Nearest on that share: Venom V3815TK at 16% and Venom V4013TK at 21%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).
07 Where this floorplan sits

11 NHTSA safety record
NHTSA holds 10 recall campaigns and 2 owner complaints (model years 2005 on) against the Venom line (a recall and a complaint are not the same thing).
Too few reports to show a pattern. 2 complaints have been filed on this line — not enough to say what fails most often. They cover structure.
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 Venom 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.
