01 What makes it unique
KZ lists the 2014 StoneRidge 41CKS at 13,820 lb dry, a GVWR of 19,000 lb, a net carrying capacity of 5,180 lb and a pin weight of 2,930 lb. Its dry weight plus its carrying capacity comes to exactly its GVWR.
It is 42' 8" long and 13' 1" high. KZ prints its tanks as 110 gal fresh, 57 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 8 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 41CKS differs from the other seven StoneRidge floorplans. Most distinctive first. How these ranks are worked out.
- Dry weight, 13,820 lb: heaviest of eight; next is the 40RSS (13,720 lb).
- Cargo capacity, 5,180 lb: second-largest of eight, between the 36IK (3,275 lb) and the 40RSS (5,280 lb).
- Cargo capacity as a share of GVWR, 27.3%: second-largest of eight, between the 36IK (21.8%) and the 40RSS (27.8%).
- Pin weight, 2,930 lb: second-heaviest of eight, between the 36IK (2,645 lb) and the 40RSS (3,040 lb).
- Length, 42 ft 8 in: second-longest of eight, between the 39BH (40 ft 10 in) and the 40RSS (42 ft 10 in).
- Pin weight as a share of dry weight, 21.2%: third-largest of eight, between the 36UL (20.4%) and the 40RSS (22.2%).
- GVWR, 19,000 lb: highest of eight, level with the 40RSS; next is the 39BH (15,500 lb).
- Fresh tank, 110 gal: largest of eight, level with the 40RSS; next are the 36IK, 36RK and four others (100 gal).
Next to the 40RSS, the nearest lighter floorplan by dry weight, the 41CKS is 100 lb heavier by dry weight, has 100 lb less cargo capacity, has a pin weight 110 lb lighter, is 2 in shorter and has a grey tank 57 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 (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.
03 The StoneRidge floorplan family
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.

04 Notes on this floorplan
What KZ does not publish for the StoneRidge 41CKS
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
13,720 lb dry and 19,000 lb GVWR, against this model’s 13,820 lb and 19,000 lb.
06 Loading it for a trip
A full 110-gallon fresh tank is about 913 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 18% of the StoneRidge 41CKS’s 5,180 lb cargo capacity, leaving 4,267 lb. Across 8 StoneRidge floorplans the water share runs 17% to 32%, and 6 give up more than this one. Nearest on that share: StoneRidge 40RSS at 17% and StoneRidge 36IK at 25%. 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 StoneRidge 40RSS, nearest on the published figures. It differs on 5 of the 8 fields both publish (this plan first): length 42 ft 8 in vs 42 ft 10 in; dry weight 13,820 lb vs 13,720 lb; cargo capacity 5,180 lb vs 5,280 lb; hitch weight 2,930 lb vs 3,040 lb; grey tank 57 gal vs 114 gal. They match on GVWR, fresh 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 StoneRidge 41CKS. Not published: sleeps, slide count, axle count, refrigerator, air conditioning, tire size (a description is published, a size is not).

11 NHTSA safety record
NHTSA holds 3 recall campaigns against the StoneRidge line (a recall and a complaint are not the same thing).
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 StoneRidge line page.
Earlier model years
The record at the top of this page is the 41CKS from 2014. The maker’s own documents for earlier model years also list the 41CKS, and those 2 years are, each from its own brochure printed here: 2012 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.
