01 What makes it unique
KZ lists the 2027 Connect Mini CM181RB at 3,980 lb unloaded (UVW), with a GVWR of 4,800 lb, a cargo carrying capacity of 820 lb and a dry hitch weight of 560 lb. Its UVW plus its cargo capacity comes to exactly its GVWR.
It is 22' 1" long and 10' 5" high with the air conditioner, with 36 gal fresh, 32 gal grey and 32 gal black tanks. Fresh water weighs about 8.3 lb per US gallon, so a full fresh tank uses roughly 299 lb of the cargo capacity before anything else is loaded.
Among the 5 Connect Mini floorplans KZ lists for 2027 with a published weight, it is number 1 by unloaded weight, in a range from 3,980 lb (CM181RB) to 5,090 lb (CM221RB). 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 Connect Mini CM181RB, 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 CM181RB differs from the other four Connect Mini floorplans. Most distinctive first. How these ranks are worked out.
- Dry weight, 3,980 lb: lightest of five; next is the CM171RK (4,090 lb).
- Dry tongue weight as a share of dry weight, 14.1%: largest of five; next are the CM171RK and CM191BHK (13.2%).
- Cargo capacity as a share of GVWR, 17.1%: second-largest of five, between the CM221RB (15.2%) and the CM231BH (17.3%).
- Dry tongue weight, 560 lb: second-heaviest of five, between the CM191BHK (550 lb) and the CM231BH (580 lb).
- Cargo capacity, 820 lb: third-smallest of five, between the CM171RK (710 lb) and the CM221RB (910 lb).
- Sleeping capacity, 3: smallest of five, level with the CM171RK; next is the CM221RB (5).
- Length, 22 ft 1 in: shared with the CM191BHK; of five, one shorter and two longer, nearest the CM171RK (21 ft 6 in) and the CM221RB (27 ft 3 in).
Next to the CM171RK, the nearest heavier floorplan by dry weight, the CM181RB is 110 lb lighter by dry weight, has 110 lb more cargo capacity, has a dry tongue weight 20 lb heavier and is 7 in longer; the two publish the same GVWR, exterior height, interior 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 (4,800 lb) and the upper loaded tongue estimate (720 lb, a rule of thumb). Your vehicle’s placard and the trailer’s own weight label govern.
Loaded range: 10–15% of GVWR on the tongue, 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 dry figure, because loaded is never lighter than dry.

04 Notes on this floorplan
What KZ does not publish for the CM181RB
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
4,090 lb UVW and 4,800 lb GVWR, against this plan’s 3,980 lb and 4,800 lb.
06 Loading it for a trip
A full 36-gallon fresh tank is about 299 lb of water (water counts as cargo: 49 CFR 571.110 S9.3.2), 36% of the CM181RB’s 820 lb cargo capacity, leaving 521 lb (174 lb per rated berth). Across 5 Connect Mini floorplans the water share runs 29% to 47%, and 2 give up more than this one. Nearest on that share: Connect Mini CM221RB at 33% and Connect Mini CM171RK at 42%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.110 S9.3.3).
