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 (7,500 lb) and the upper loaded pin estimate (1,875 lb, a rule of thumb). Your vehicle’s placard and the trailer’s own weight label govern.
Loaded range: 15–25% of GVWR on the pin, 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 Sportsmen Fifth Wheel 231RK
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
7,170 lb dry and 8,500 lb GVWR, against this model’s 6,340 lb and 7,500 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), 32% of the Sportsmen Fifth Wheel 231RK’s 1,160 lb cargo capacity, leaving 786 lb (157 lb per rated berth). Across 6 Sportsmen Fifth Wheel floorplans the water share runs 23% to 39%, and 1 gives up more than this one. Nearest on that share: Sportsmen Fifth Wheel 303RL at 30% and Sportsmen Fifth Wheel 302BHK at 39%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.110 S9.3.3).
