2026 Forest River IBEX25RLSS

The IBEX 25RLSS has 1,500 lbs of cargo capacity between 5,743 lbs dry and its 7,243 lbs GVWR, 21% of that rating; filling its 40-gallon fresh tank at 8.3 lb a gallon uses 332 lbs of it (how to read trailer weights).

Tongue weight is 850 lbs, 15% of the dry weight as published; it rises as the trailer is loaded and counts against the tow vehicle’s tongue-weight and payload limits (tongue weight by size).

Off hookups: 70 gallons of grey and black capacity against 40 gallons of fresh water, so fresh water runs out first (tank sizes by length).

Against the rest of the IBEX roster this is the 13th of 16 floorplans by dry weight, in a line that runs from 3,778 lbs to 6,733 lbs. It sits in the heavier third of the line.

Plan the tow on loaded weight, not the 5,743 lbs dry figure: half the published cargo capacity brings this plan to about 6,493 lbs, and the published GVWR of 7,243 lbs is the limit (how to read trailer weights).

Forest River’s line listing and this floorplan’s own factory page agree on all 4 shared figures. Dry weight plus cargo capacity equals the published GVWR exactly. A missing row means Forest River does not publish that figure (how figures are verified).

Forest River's own description of this floorplan reads: “The 25RLSS front master bedroom features a queen-sized bed with dual wardrobes, providing ample storage space. The walk-through bath offers convenient access from both the living area and the bedroom. The rear living space boasts a tri-fold sofa slide-out and a booth dinette, creating a comfortable area for relaxation and dining. The well-equipped kitchen includes a microwave air fryer, refrigerator and large…” That is the factory's marketing copy rather than a specification, and nothing in it is treated as a verified field on this page - layout descriptions, sleeping arrangements and feature claims in factory copy are not carried into the spec table unless the factory also publishes them as specifications.

How the 25RLSS differs from the other fifteen IBEX floorplans. Most distinctive first. How these ranks are worked out.

• Tongue weight, 850 lb: second-heaviest of sixteen, between the 20FKDS (800 lb) and the 25RBH (1,030 lb).
• Dry weight, 5,743 lb: fourth-heaviest of sixteen, between the 20FKDS (5,678 lb) and the 25RBH (6,338 lb).
• GVWR, 7,243 lb: fourth-highest of sixteen, between the 20FKDS (7,178 lb) and the 25RBH (7,838 lb).
• Length, 29 ft: fourth-longest of sixteen, between the 20FKDS (27 ft 7 in) and the 25MLB (29 ft 9 in).
• Cargo capacity as a share of GVWR, 20.7%: sixth-smallest of sixteen, between the 25RBH (19.1%) and the 20FKDS (20.9%).
• Tongue weight as a share of dry weight, 14.8%: shared with the 19MSB; of sixteen, thirteen smaller and one larger, nearest the 23MBH (14.7%) and the 25RBH (16.3%).
• Grey tank, 40 gal: shared with the 16MKS, 20MDS and two others; of sixteen, eight smaller and three larger, nearest the 16MBJ, 16MKD and six others (30 gal) and the 20FKDS, 25MLB and 26BRE (60 gal).

Next to the 20FKDS, the nearest lighter floorplan by dry weight, the 25RLSS is 65 lb heavier by dry weight, has a GVWR 65 lb higher, has a tongue weight 50 lb heavier, is 1 ft 5 in longer and has a grey tank 20 gal smaller; the two publish the same cargo capacity, exterior height, fresh tank and black tank.

Next to the 25RBH, the nearest heavier floorplan by dry weight, the 25RLSS is 595 lb lighter by dry weight, has a GVWR 595 lb lower, has a tongue weight 180 lb lighter, is 3 ft 11 in shorter and has a grey tank 10 gal larger; the two publish the same cargo capacity, exterior height, fresh tank and black tank.

IBEX is Forest River's lightweight four-season travel trailer, built at the company's Outdoors RV-adjacent end of the travel-trailer range rather than in the value tier. The roster runs from a 16-foot single-axle at under 4,100 lb dry to a tandem-axle 26-footer. Forest River publishes a full weight and capacity block for every floorplan, which is why this line could be catalogued completely rather than partially.

A full 40-gallon fresh tank is about 332 lb of water (water counts as cargo: 49 CFR 571.110 S9.3.2), 22% of the 25RLSS’s 1,500 lb cargo capacity, leaving 1,168 lb. Across 16 IBEX floorplans the water share runs 14% to 36%, and 3 give up more than this one. Nearest on that share: IBEX 20FKDS at 22% and IBEX 23MBH at 22%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.110 S9.3.3).
