01 What makes it unique
KZ lists the 2014 StoneRidge 38FL at 11,890 lb dry, a GVWR of 15,000 lb, a net carrying capacity of 3,110 lb and a pin weight of 2,210 lb. Its dry weight plus its carrying capacity comes to exactly its GVWR.
It is 39' 11" long and 13' high. KZ prints its tanks as 100 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 3 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 38FL differs from the other seven StoneRidge floorplans. Most distinctive first. How these ranks are worked out.
- Pin weight, 2,210 lb: lightest of eight; next is the 36RLB (2,280 lb).
- Dry weight, 11,890 lb: third-lightest of eight, between the 36RLB (11,730 lb) and the 36UL (11,940 lb).
- Pin weight as a share of dry weight, 18.6%: third-smallest of eight, between the 36RK (18.4%) and the 36RLB (19.4%).
- Exterior height, 13 ft: third-lowest of eight, between the 36RLB (12 ft 11 in) and the 36IK, 36RK and three others (13 ft 1 in).
- Cargo capacity, 3,110 lb: fourth-largest of eight, between the 36UL (3,060 lb) and the 36IK (3,275 lb).
- Cargo capacity as a share of GVWR, 20.7%: fourth-largest of eight, between the 36UL (20.4%) and the 36IK (21.8%).
- Length, 39 ft 11 in: fourth-longest of eight, between the 36RK and 36UL (38 ft 8 in) and the 39BH (40 ft 10 in).
- GVWR, 15,000 lb: shared with the 36IK and 36UL; of eight, one lower and four higher, nearest the 36RLB (14,500 lb) and the 36RK (15,400 lb).
Next to the 36RLB, the nearest lighter floorplan by dry weight, the 38FL is 160 lb heavier by dry weight, has a GVWR 500 lb higher, has 340 lb more cargo capacity, has a pin weight 70 lb lighter, is 2 ft longer and stands 1 in taller; the two publish the same interior height, fresh tank, grey tank and black tank.
Next to the 36UL, the nearest heavier floorplan by dry weight, the 38FL is 50 lb lighter by dry weight, has 50 lb more cargo capacity, has a pin weight 230 lb lighter, is 1 ft 3 in longer and stands 1 in lower; the two publish the same GVWR, 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 (15,000 lb) and the upper loaded pin estimate (3,750 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).

04 Notes on this floorplan
What KZ does not publish for the StoneRidge 38FL
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
11,730 lb dry and 14,500 lb GVWR, against this model’s 11,890 lb and 15,000 lb.
11,940 lb dry and 15,000 lb GVWR, against this model’s 11,890 lb and 15,000 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), 27% of the StoneRidge 38FL’s 3,110 lb cargo capacity, leaving 2,280 lb. Across 8 StoneRidge floorplans the water share runs 17% to 32%, and 4 give up more than this one. Nearest on that share: StoneRidge 36IK at 25% and StoneRidge 36UL at 27%. 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 36UL, nearest on the published figures. It differs on 4 of the 8 fields both publish (this plan first): length 39 ft 11 in vs 38 ft 8 in; dry weight 11,890 lb vs 11,940 lb; cargo capacity 3,110 lb vs 3,060 lb; hitch weight 2,210 lb vs 2,440 lb. They match on GVWR, fresh tank, grey tank and black tank.
| StoneRidge plans | This plan | Position, low to high | Range |
|---|---|---|---|
| GVWR (lb) | 15,000 | 2–4 of 8 | 14,500–19,000 |
| Dry weight (lb) | 11,890 | 3 of 8 | 11,725–13,820 |
| Cargo capacity (lb) | 3,110 | 5 of 8 | 2,580–5,280 |
| Hitch weight (lb) | 2,210 | 1 of 8 | 2,210–3,040 |
| Length | 39 ft 11 in | 5 of 8 | 37 ft 8 in–42 ft 10 in |
| Fresh tank (gal) | 100 | 1–6 of 8 | 100–110 |
| Grey tank (gal) | 57 | 1–5 of 8 | 57–114 |

09 What this page publishes, and what it does 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 38FL from 2014. The maker’s own documents for earlier model years also list the 38FL, 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.

Source for 2013. Printed in KZ RV’s StoneRidge brochure (www.kz-rv.com). The document itself prints no model year; KZ RV files it under 2013 in its own brochure folder. Dry weight plus cargo capacity equals the printed GVWR exactly (11,870 + 3,130 = 15,000 lb). Nothing in this record is copied from another model year.
NHTSA record for 2013 StoneRidge
2 recall campaigns filed with NHTSA name the StoneRidge for model year 2013:
No owner complaint filed with NHTSA names the StoneRidge for model year 2013. NHTSA files recalls and complaints by line and model year, not by floorplan, so a campaign listed here may not affect every StoneRidge floorplan; the recall notice says which units it covers.

2 recall campaigns filed with NHTSA name the StoneRidge for model year 2012:
