Every number on this page was read on 7 Nov 2026 from Forest River’s own 2026 IBEX floorplan page for the IBEX 16RKB, whose heading names the model year 2026.
How the 16RKB differs from the other seventeen IBEX floorplans. Most distinctive first. How these ranks are worked out.

- Length, 14 ft 11 in: shortest of eighteen; next is the 16MRJ (19 ft 10 in).
- Tongue weight as a share of dry weight, 11.1%: second-smallest of eighteen, between the 25MLB (10%) and the 20MKB (11.2%).
- Exterior height, 10 ft 10 in: shared with the 16MBJ, 16MKD and two others; of eighteen, three lower and ten taller, nearest the 19BRK, 19MBH and 19MSB (10 ft 9 in) and the 16MKS, 20FKDS and eight others (11 ft 3 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 (4,524 lb) and the upper loaded tongue estimate (679 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 Forest River does not publish for the IBEX 16RKB
Forest River prints no tire size, interior height, 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
5,113 lb dry and 6,613 lb GVWR, against this model’s 3,024 lb and 4,524 lb.
06 Loading it for a trip
A full 30-gallon fresh tank is about 249 lb of water (water counts as cargo: 49 CFR 571.110 S9.3.2), 17% of the IBEX 16RKB’s 1,500 lb cargo capacity, leaving 1,251 lb. Across 18 IBEX floorplans the water share runs 14% to 36%, and 13 give up more than this one. Nearest on that share: IBEX 16MKD at 17% and IBEX 16MBJ 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 IBEX 16MBJ, nearest on the published figures. It differs on 5 of the 8 fields both publish (this plan first): length 14 ft 11 in vs 21 ft 8 in; dry weight 3,024 lb vs 4,088 lb; GVWR 4,524 lb vs 5,585 lb; cargo capacity 1,500 lb vs 1,497 lb; hitch weight 335 lb vs 485 lb. They match on fresh tank, grey tank and black tank.

11 NHTSA safety record
NHTSA holds 8 recall campaigns and 3 owner complaints (model years 2005 on) against the IBEX line (a recall and a complaint are not the same thing).
Too few reports to show a pattern. 3 complaints have been filed on this line — not enough to say what fails most often. They cover unknown or other.
Recall coverage here is not complete, and complaints are owners’ unverified reports (how this record is built). Check a specific VIN at NHTSA before you buy. Full tables are on the IBEX line page.
