01 What makes it unique
KZ lists the 2013 Rock Climber CRC222 at 5,340 lb dry, a GVWR of 7,940 lb, a net carrying capacity of 2,735 lb and a tongue weight of 345 lb. KZ’s own figures do not add up — a conflict, stated not resolved: 5,340 lb dry plus 2,735 lb carrying capacity is 8,075 lb, against a printed GVWR of 7,940 lb. All three are shown as KZ prints them and none is corrected; the federal label on the trailer is the one to trust.
It is 32' 9" long and 10' 8" high. KZ prints its tanks as 58 gal fresh, 32 gal grey, 32 gal black.
Among the 4 Rock Climber floorplans KZ’s Rock Climber brochure (filed in KZ’s 2013 brochure folder; the brochure prints no year) lists with a published dry weight, it is number 4 from the lightest, in a range from 4,340 lb (Rock Climber CRC170S) to 5,340 lb (Rock Climber CRC222). Every figure in that comparison is KZ’s, for the same model year.
Every number on this page was read on 6 Nov 2026 from KZ’s Rock Climber brochure (filed in KZ’s 2013 brochure folder; the brochure prints no year); model year 2013 comes from where the maker files it on its own site, not from the document’s text.
How the CRC222 differs from the other three Rock Climber floorplans. Most distinctive first. How these ranks are worked out.
- Dry weight, 5,340 lb: heaviest of four; next is the CRC210KS (5,188 lb).
- Cargo capacity, 2,735 lb: second-largest of four, between the CRC170S (2,660 lb) and the CRC210KS (2,752 lb).
- Tongue weight, 345 lb: second-heaviest of four, between the CRC210KS (308 lb) and the CRC220 (390 lb).
- Tongue weight as a share of dry weight, 6.5%: second-largest of four, between the CRC210KS (5.9%) and the CRC220 (7.9%).
- Length, 32 ft 9 in: second-shortest of four, between the CRC220 (32 ft 4 in) and the CRC210KS (32 ft 10 in).
- GVWR, 7,940 lb: highest of four, level with the CRC210KS; next are the CRC170S and CRC220 (7,000 lb).
- Exterior height, 10 ft 8 in: tallest of four, level with the CRC170S; next are the CRC210KS and CRC220 (10 ft 7 in).
Next to the CRC210KS, the nearest lighter floorplan by dry weight, the CRC222 is 152 lb heavier by dry weight, has 17 lb less cargo capacity, has a tongue weight 37 lb heavier, is 1 in shorter and stands 1 in taller; 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 (7,940 lb) and the upper loaded tongue estimate (1,191 lb, a rule of thumb). Your vehicle’s placard and the trailer’s own weight label govern. This floorplan’s published dry weight plus cargo capacity comes to 8,075 lb, which is not its published GVWR; the check uses the published GVWR.
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).

04 Notes on this floorplan
What KZ does not publish for the Rock Climber CRC222
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
5,188 lb dry and 7,940 lb GVWR, against this model’s 5,340 lb and 7,940 lb.
06 Loading it for a trip
A full 58-gallon fresh tank is about 481 lb of water (water counts as cargo: 49 CFR 571.110 S9.3.2), 18% of the Rock Climber CRC222’s 2,735 lb cargo capacity, leaving 2,254 lb. Across 4 Rock Climber floorplans the water share runs 16% to 24%, and 1 gives up more than this one. Nearest on that share: Rock Climber CRC210KS at 17% and Rock Climber CRC220 at 24%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.110 S9.3.3).
