01 What makes it unique
KZ lists the 2027 Ridgeway 31RL at 10,160 lb unloaded (UVW), with a GVWR of 12,995 lb, a cargo carrying capacity of 2,835 lb and a dry pin weight of 1,871 lb. Its UVW plus its cargo capacity comes to exactly its GVWR.
It is 35' 2" long and 13' 3" high with the air conditioner, with 76 gal fresh, 50 gal grey and 50 gal black tanks. Fresh water weighs about 8.3 lb per US gallon, so a full fresh tank uses roughly 631 lb of the cargo capacity before anything else is loaded.
Among the 7 Ridgeway floorplans KZ lists for 2027 with a published weight, it is number 4 by unloaded weight, in a range from 7,900 lb (R24ML) to 12,630 lb (38TBL). 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 own floorplan page for the Ridgeway 31RL, whose floorplan drawing KZ labels 2027. KZ notes that its UVW reflects a rolling average for the model and that your trailer will vary with optional equipment.
How the 31RL differs from the other six Ridgeway floorplans. Most distinctive first. How these ranks are worked out.
- Cargo capacity, 2,835 lb: largest of seven; next is the 32ML (2,735 lb).
- Dry pin weight, 1,871 lb: third-heaviest of seven, between the 32ML (1,850 lb) and the 36MBL (2,280 lb).
- Dry pin weight as a share of dry weight, 18.4%: third-largest of seven, between the 32ML (18%) and the 36MBL (18.7%).
- Dry weight, 10,160 lb: fourth-lightest of seven, between the R27RS and R28BH (8,300 lb) and the 32ML (10,260 lb).
- Cargo capacity as a share of GVWR, 21.8%: fourth-smallest of seven, between the 32ML (21%) and the R27RS and R28BH (24.5%).
- Length, 35 ft 2 in: fourth-shortest of seven, between the R28BH (31 ft 9 in) and the 32ML (35 ft 4 in).
- GVWR, 12,995 lb: shared with the 32ML; of seven, three lower and two higher, nearest the R27RS and R28BH (11,000 lb) and the 36MBL (14,495 lb).
- Sleeping capacity, 4: shared with the 32ML and R27RS; of seven, one smaller and three larger, nearest the R24ML (3) and the 38TBL (6).
Next to the R27RS, the nearest lighter floorplan by dry weight, the 31RL is 1,860 lb heavier by dry weight, has a GVWR 1,995 lb higher, has 135 lb more cargo capacity, has a dry pin weight 471 lb heavier, is 3 ft 7 in longer and stands 8 in taller; the two publish the same fresh tank, grey tank, black tank and sleeping capacity.
Next to the 32ML, the nearest heavier floorplan by dry weight, the 31RL is 100 lb lighter by dry weight, has 100 lb more cargo capacity, has a dry pin weight 21 lb heavier and is 2 in shorter; the two publish the same GVWR, exterior height, fresh tank, grey tank, black tank and sleeping capacity.

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 (12,995 lb) and the upper loaded pin estimate (3,249 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 31RL
KZ’s page prints no axle count and no price against this floorplan, so none is given. Nothing is filled from a sibling floorplan, 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
8,300 lb UVW and 11,000 lb GVWR, against this plan’s 10,160 lb and 12,995 lb.
10,260 lb UVW and 12,995 lb GVWR, against this plan’s 10,160 lb and 12,995 lb.
06 Loading it for a trip
A full 76-gallon fresh tank is about 631 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 22% of the 31RL’s 2,835 lb cargo capacity, leaving 2,204 lb (551 lb per rated berth). Across 7 Ridgeway floorplans the water share runs 22% to 27%, and this plan’s is the lowest. Nearest on that share: Ridgeway 32ML at 23%. 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 Ridgeway 32ML, nearest on the published figures. It differs on 4 of the 9 fields both publish (this plan first): length 35 ft 2 in vs 35 ft 4 in; dry weight 10,160 lb vs 10,260 lb; cargo capacity 2,835 lb vs 2,735 lb; hitch weight 1,871 lb vs 1,850 lb. They match on sleeps, GVWR, fresh tank, grey tank and black tank.
