01 What makes it unique
KZ lists the 2027 Connect C221ML at 5,660 lb unloaded (UVW), with a GVWR of 7,320 lb, a cargo carrying capacity of 1,660 lb and a dry hitch weight of 640 lb. Its UVW plus its cargo capacity comes to exactly its GVWR.
It is 26' 5" long and 11' 2" high with the air conditioner, with 45 gal fresh, 38 gal grey and 38 gal black tanks. Fresh water weighs about 8.3 lb per US gallon, so a full fresh tank uses roughly 374 lb of the cargo capacity before anything else is loaded.
Among the 10 Connect floorplans KZ lists for 2027 with a published weight, it is number 1 by unloaded weight, in a range from 5,660 lb (C221ML) to 8,780 lb (C313MK). 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 C221ML, 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. KZ marks the floorplan as new.
How the C221ML differs from the other nine Connect floorplans. Most distinctive first. How these ranks are worked out.
- Dry weight, 5,660 lb: lightest of ten; next is the C241RLK (6,120 lb).
- Dry tongue weight, 640 lb: lightest of ten; next is the C241RLK (730 lb).
- Length, 26 ft 5 in: shortest of ten; next is the C241RLK (28 ft 11 in).
- Sleeping capacity, 2: smallest of ten; next are the C271RL and C312RE (4).
- GVWR, 7,320 lb: second-lowest of ten, between the C241RLK (7,265 lb) and the C261RB (8,300 lb).
- Cargo capacity as a share of GVWR, 22.7%: second-largest of ten, between the C303RK (20.9%) and the C271RL (23.4%).
- Dry tongue weight as a share of dry weight, 11.3%: second-smallest of ten, between the C302FBK (11%) and the C271RL (11.7%).
- Cargo capacity, 1,660 lb: fifth-smallest of ten, between the C261RB (1,625 lb) and the C312RE (1,690 lb).
- Exterior height, 11 ft 2 in: lowest of ten, level with the C241RLK and C261RB; next are the C271RBK, C271RL and two others (11 ft 4 in).
- Grey tank, 38 gal: smallest of ten, level with the C241RLK, C271RL and two others; next are the C261RB, C271RBK and three others (76 gal).
Next to the C241RLK, the nearest heavier floorplan by dry weight, the C221ML is 460 lb lighter by dry weight, has a GVWR 55 lb higher, has 515 lb more cargo capacity, has a dry tongue weight 90 lb lighter, is 2 ft 6 in shorter and sleeps four fewer; the two publish the same exterior height, 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 (7,320 lb) and the upper loaded tongue estimate (1,098 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).

KZ lists 14 Connect floorplans. Every 2027 plan with a published weight has a page here; the rest are catalogued with the reason against each.
04 Notes on this floorplan
What KZ does not publish for the C221ML
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
6,120 lb UVW and 7,265 lb GVWR, against this plan’s 5,660 lb and 7,320 lb.
06 Loading it for a trip
A full 45-gallon fresh tank is about 374 lb of water (water counts as cargo: 49 CFR 571.110 S9.3.2), 23% of the C221ML’s 1,660 lb cargo capacity, leaving 1,286 lb (643 lb per rated berth). Across 10 Connect floorplans the water share runs 17% to 33%, and 4 give up more than this one. Nearest on that share: Connect C312RE at 22% and Connect C261RB at 23%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.110 S9.3.3).
07 Where this floorplan sits
Closest sibling: the Connect C241RLK, nearest on the published figures. It differs on 6 of the 9 fields both publish (this plan first): length 26 ft 5 in vs 28 ft 11 in; sleeps 2 vs 6; dry weight 5,660 lb vs 6,120 lb; GVWR 7,320 lb vs 7,265 lb; cargo capacity 1,660 lb vs 1,145 lb; hitch weight 640 lb vs 730 lb. They match on fresh tank, grey tank and black tank.
