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 2 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 3517DK differs from the other five Sidewinder floorplans. Most distinctive first. How these ranks are worked out.

• Dry weight, 10,780 lb: second-lightest of six, between the 3214DK (10,470 lb) and the 3511DK (11,370 lb).
• Cargo capacity as a share of GVWR, 28.1%: second-largest of six, between the 3814DK (26.9%) and the 3214DK (30.2%).
• Pin weight, 2,640 lb: second-heaviest of six, between the 3814DK (2,620 lb) and the 3214DK (2,780 lb).
• Pin weight as a share of dry weight, 24.5%: second-largest of six, between the 3814DK (21.1%) and the 3214DK (26.6%).
• Length, 37 ft 11 in: second-shortest of six, between the 3214DK (34 ft 11 in) and the 3511DK (38 ft 4 in).

KZ’s Sidewinder brochure (filed in KZ’s 2018 brochure folder; the brochure prints no year) lists 6 Sidewinder floorplans; every one with a printed weight has a page here.

A full 116-gallon fresh tank is about 963 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 23% of the Sidewinder 3517DK’s 4,215 lb cargo capacity, leaving 3,252 lb. Across 6 Sidewinder floorplans the water share runs 21% to 29%, and 3 give up more than this one. Nearest on that share: Sidewinder 3214DK at 21% and Sidewinder 3511DK at 27%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).

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.

The record at the top of this page is the 3517DK from 2018. The maker’s own documents for earlier model years also list the 3517DK, and that year is printed here: 2017. The figures change from year to year, so check the year on the trailer’s own label. A field a year’s brochure does not print reads “Not published” and is never filled from another year.
