2014 KZStoneRidge 36RK

KZ lists the 2014 StoneRidge 36RK at 12,420 lb dry, a GVWR of 15,400 lb, a net carrying capacity of 2,980 lb and a pin weight of 2,290 lb. Its dry weight plus its carrying capacity comes to exactly its GVWR.

It is 38' 8" long and 13' 1" high. KZ prints its tanks as 100 gal fresh, 114 gal grey, 57 gal black.

Among the 8 StoneRidge floorplans KZ’s StoneRidge brochure (filed in KZ’s 2014 brochure folder; the brochure prints no year) lists with a published dry weight, it is number 5 from the lightest, in a range from 11,725 lb (StoneRidge 36IK) to 13,820 lb (StoneRidge 41CKS). 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 StoneRidge brochure (filed in KZ’s 2014 brochure folder; the brochure prints no year); model year 2014 comes from where the maker files it on its own site, not from the document’s text.

How the 36RK differs from the other seven StoneRidge floorplans. Most distinctive first. How these ranks are worked out.

• Pin weight as a share of dry weight, 18.4%: second-smallest of eight, between the 39BH (17.7%) and the 38FL (18.6%).
• Cargo capacity, 2,980 lb: third-smallest of eight, between the 36RLB (2,770 lb) and the 36UL (3,060 lb).
• Cargo capacity as a share of GVWR, 19.4%: third-smallest of eight, between the 36RLB (19.1%) and the 36UL (20.4%).
• Dry weight, 12,420 lb: fourth-heaviest of eight, between the 36UL (11,940 lb) and the 39BH (12,920 lb).
• GVWR, 15,400 lb: fourth-highest of eight, between the 36IK, 36UL and 38FL (15,000 lb) and the 39BH (15,500 lb).
• Grey tank, 114 gal: largest of eight, level with the 39BH and 40RSS; next are the 36IK, 36RLB and three others (57 gal).
• Pin weight, 2,290 lb: shared with the 39BH; of eight, two lighter and four heavier, nearest the 36RLB (2,280 lb) and the 36UL (2,440 lb).
• Length, 38 ft 8 in: shared with the 36UL; of eight, two shorter and four longer, nearest the 36RLB (37 ft 11 in) and the 38FL (39 ft 11 in).

Next to the 36UL, the nearest lighter floorplan by dry weight, the 36RK is 480 lb heavier by dry weight, has a GVWR 400 lb higher, has 80 lb less cargo capacity, has a pin weight 150 lb lighter and has a grey tank 57 gal larger; the two publish the same length, exterior height, interior height, fresh tank and black tank.

Next to the 39BH, the nearest heavier floorplan by dry weight, the 36RK is 500 lb lighter by dry weight, has a GVWR 100 lb lower, has 400 lb more cargo capacity, is 2 ft 2 in shorter and stands 5 in taller; the two publish the same pin weight, interior height, fresh tank, grey tank and black tank.

KZ’s StoneRidge brochure (filed in KZ’s 2014 brochure folder; the brochure prints no year) lists 8 StoneRidge floorplans; every one with a printed weight has a page here.

A full 100-gallon fresh tank is about 830 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 28% of the StoneRidge 36RK’s 2,980 lb cargo capacity, leaving 2,150 lb. Across 8 StoneRidge floorplans the water share runs 17% to 32%, and 2 give up more than this one. Nearest on that share: StoneRidge 36UL at 27% and StoneRidge 36RLB at 30%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).

The record at the top of this page is the 36RK from 2014. The maker’s own documents for earlier model years also list the 36RK, and those 3 years are, each from its own brochure printed here: 2011 to 2013. 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.
