2026 Forest River IBEX23MBH

The IBEX 23MBH has 1,492 lbs of cargo capacity between 5,108 lbs dry and its 6,600 lbs GVWR, 23% 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 750 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 11th 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 5,108 lbs dry figure: half the published cargo capacity brings this plan to about 5,854 lbs, and the published GVWR of 6,600 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 23MBH is a spacious, family-friendly travel trailer that combines comfort and versatility. A front Murphy bed converts to a sofa for added living space, while rear double bunks provide room for guests or kids. The slide-out dinette expands the interior, and the full kitchen—with microwave, air fryer, and pantry—makes meals easy. A full bath adds comfort, and exteriors features like an enclosed underbelly and 16'…” 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 23MBH differs from the other fifteen IBEX floorplans. Most distinctive first. How these ranks are worked out.

• Cargo capacity, 1,492 lb: fourth-smallest of sixteen, between the 19MSB (1,275 lb) and the 16MBJ (1,497 lb).
• Tongue weight as a share of dry weight, 14.7%: fourth-largest of sixteen, between the 16MKD (14.2%) and the 19MSB and 25RLSS (14.8%).
• Tongue weight, 750 lb: fifth-heaviest of sixteen, between the 19MSB (710 lb) and the 26BRE (760 lb).
• Dry weight, 5,108 lb: sixth-heaviest of sixteen, between the 20MDS (4,963 lb) and the 20FKDS (5,678 lb).
• GVWR, 6,600 lb: sixth-highest of sixteen, between the 20MDS (6,463 lb) and the 20FKDS (7,178 lb).
• Length, 26 ft 2 in: sixth-longest of sixteen, between the 19BRK and 20MKB (25 ft) and the 20FKDS (27 ft 7 in).
• Cargo capacity as a share of GVWR, 22.6%: eighth-largest of sixteen, between the 19MSB (21%) and the 20MDS (23.2%).

Next to the 20MDS, the nearest lighter floorplan by dry weight, the 23MBH is 145 lb heavier by dry weight, has a GVWR 137 lb higher, has 8 lb less cargo capacity, has a tongue weight 120 lb heavier and is 1 ft 11 in longer; the two publish the same exterior height, fresh tank, grey tank and black tank.

Next to the 20FKDS, the nearest heavier floorplan by dry weight, the 23MBH is 570 lb lighter by dry weight, has a GVWR 578 lb lower, has 8 lb less cargo capacity, has a tongue weight 50 lb lighter, is 1 ft 5 in shorter and has a grey tank 20 gal smaller; the two publish the same 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 23MBH’s 1,492 lb cargo capacity, leaving 1,160 lb. Across 16 IBEX floorplans the water share runs 14% to 36%, and 2 give up more than this one. Nearest on that share: IBEX 20FKDS at 22% and IBEX 19QRB at 33%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.110 S9.3.3).
