01 What makes it unique
KZ lists the 2013 Rock Climber CRC220 at 4,960 lb dry, a GVWR of 7,000 lb, a net carrying capacity of 2,040 lb and a tongue weight of 390 lb. Its dry weight plus its carrying capacity comes to exactly its GVWR.
It is 32' 4" long and 10' 7" 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 2 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.

- Dry weight, 4,960 lb: second-lightest of four, between the CRC170S (4,340 lb) and the CRC210KS (5,188 lb).
- GVWR, 7,000 lb: lowest of four, level with the CRC170S; next are the CRC210KS and CRC222 (7,940 lb).
- Exterior height, 10 ft 7 in: lowest of four, level with the CRC210KS; next are the CRC170S and CRC222 (10 ft 8 in).

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 (7,000 lb) and the upper loaded tongue estimate (1,050 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).

04 Notes on this floorplan
What KZ does not publish for the Rock Climber CRC220
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
4,340 lb dry and 7,000 lb GVWR, against this model’s 4,960 lb and 7,000 lb.
5,188 lb dry and 7,940 lb GVWR, against this model’s 4,960 lb and 7,000 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), 24% of the Rock Climber CRC220’s 2,040 lb cargo capacity, leaving 1,559 lb. Across 4 Rock Climber floorplans the water share runs 16% to 24%, and this plan’s is the highest. Nearest on that share: Rock Climber CRC222 at 18%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.110 S9.3.3).
