01 What makes it unique
KZ lists the 2013 Rock Climber CRC170S at 4,340 lb dry, a GVWR of 7,000 lb, a net carrying capacity of 2,660 lb and a tongue weight of 230 lb. Its dry weight plus its carrying capacity comes to exactly its GVWR.
It is 39' 3" long and 10' 8" high. KZ prints its tanks as 50 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 1 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, 4,340 lb: lightest of four; next is the CRC220 (4,960 lb).
- Cargo capacity as a share of GVWR, 38%: largest of three; next is the CRC210KS (34.7%).
- Tongue weight, 230 lb: lightest of four; next is the CRC210KS (308 lb).
- Tongue weight as a share of dry weight, 5.3%: smallest of four; next is the CRC210KS (5.9%).

04 Notes on this floorplan
What KZ does not publish for the Rock Climber CRC170S
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
4,960 lb dry and 7,000 lb GVWR, against this model’s 4,340 lb and 7,000 lb.
06 Loading it for a trip
A full 50-gallon fresh tank is about 415 lb of water (water counts as cargo: 49 CFR 571.110 S9.3.2), 16% of the Rock Climber CRC170S’s 2,660 lb cargo capacity, leaving 2,245 lb. Across 4 Rock Climber floorplans the water share runs 16% to 24%, and this plan’s is the lowest. Nearest on that share: Rock Climber CRC210KS at 17%. 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 Rock Climber CRC210KS, nearest on the published figures.
