01 What makes it unique
KZ lists the 2018 Sidewinder 3914TK at 13,500 lb dry, a GVWR of 17,000 lb, a net carrying capacity of 3,500 lb and a pin weight of 2,600 lb. Its dry weight plus its carrying capacity comes to exactly its GVWR.
It is 46' 6" long and 13' 4" high. KZ prints its tanks as 116 gal fresh, 57 gal grey, 57 gal black.
Among the 6 Sidewinder floorplans KZ’s Sidewinder brochure (filed in KZ’s 2018 brochure folder; the brochure prints no year) lists with a published dry weight, it is number 6 from the lightest, in a range from 10,470 lb (Sidewinder 3214DK) to 13,500 lb (Sidewinder 3914TK). 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 Sidewinder brochure (filed in KZ’s 2018 brochure folder; the brochure prints no year); model year 2018 comes from where the maker files it on its own site, not from the document’s text.
How the 3914TK differs from the other five Sidewinder floorplans. Most distinctive first. How these ranks are worked out.
- Dry weight, 13,500 lb: heaviest of six; next is the 3814DK (12,430 lb).
- Cargo capacity as a share of GVWR, 20.6%: smallest of six; next is the 3610DK (22.4%).
- Pin weight as a share of dry weight, 19.3%: smallest of six; next is the 3610DK (20.9%).
- Length, 46 ft 6 in: longest of six; next is the 3814DK (41 ft 4 in).
- Cargo capacity, 3,500 lb: second-smallest of six, between the 3610DK (3,355 lb) and the 3511DK (3,625 lb).
- Pin weight, 2,600 lb: third-lightest of six, between the 3610DK (2,430 lb) and the 3814DK (2,620 lb).
- GVWR, 17,000 lb: highest of six, level with the 3814DK; next are the 3214DK, 3511DK and two others (14,995 lb).
Next to the 3814DK, the nearest lighter floorplan by dry weight, the 3914TK is 1,070 lb heavier by dry weight, has 1,070 lb less cargo capacity, has a pin weight 20 lb lighter and is 5 ft 2 in longer; the two publish the same GVWR, exterior height, interior height, fresh tank, grey 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 (17,000 lb) and the upper loaded pin estimate (4,250 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.
03 The Sidewinder floorplan family

04 Notes on this floorplan
What KZ does not publish for the Sidewinder 3914TK
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
12,430 lb dry and 17,000 lb GVWR, against this model’s 13,500 lb and 17,000 lb.
06 Loading it for a trip
A full 116-gallon fresh tank is about 963 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 28% of the Sidewinder 3914TK’s 3,500 lb cargo capacity, leaving 2,537 lb. Across 6 Sidewinder floorplans the water share runs 21% to 29%, and 1 gives up more than this one. Nearest on that share: Sidewinder 3511DK at 27% and Sidewinder 3610DK at 29%. 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
Closest sibling: the Sidewinder 3814DK, nearest on the published figures. It differs on 4 of the 8 fields both publish (this plan first): length 46 ft 6 in vs 41 ft 4 in; dry weight 13,500 lb vs 12,430 lb; cargo capacity 3,500 lb vs 4,570 lb; hitch weight 2,600 lb vs 2,620 lb. They match on GVWR, fresh tank, grey tank and black tank.
