2026 Forest River IBEX19MBH

The IBEX 19MBH has 1,500 lbs of cargo capacity between 4,484 lbs dry and its 5,984 lbs GVWR, 25% of that rating; filling its 30-gallon fresh tank at 8.3 lb a gallon uses 249 lbs of it (how to read trailer weights).

Tongue weight is 585 lbs, 13% 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: 60 gallons of grey and black capacity against 30 gallons of fresh water, so fresh water runs out first (tank sizes by length).

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

Plan the tow on loaded weight, not the 4,484 lbs dry figure: half the published cargo capacity brings this plan to about 5,234 lbs, and the published GVWR of 5,984 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: “With sleeping for up to 5, the 19MBH is equipped to take the whole family. This simple-to-use, no-slide model is equipped with a full residential queen bed up front, and full size 44”x74” bunks in the back. The bottom bunk also folds up, and from the outside compartment door, larger items can be stored and accessed easily. After waking up, the murphy queen bed up front folds up easily to expose a couch, which…” 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 19MBH differs from the other fifteen IBEX floorplans. Most distinctive first. How these ranks are worked out.

• Cargo capacity as a share of GVWR, 25.1%: fourth-largest of sixteen, between the 19BRK (23.5%) and the 16MBJ (26.8%).
• Dry weight, 4,484 lb: sixth-lightest of sixteen, between the 19QRB (4,168 lb) and the 19MSB (4,809 lb).
• GVWR, 5,984 lb: sixth-lowest of sixteen, between the 16MBJ (5,585 lb) and the 19MSB (6,084 lb).
• Exterior height, 10 ft 9 in: lowest of sixteen, level with the 19BRK and 19MSB; next are the 16MBJ, 16MKD and two others (10 ft 10 in).
• Tongue weight, 585 lb: seventh-lightest of sixteen, between the 16MKD (570 lb) and the 19BRK (610 lb).
• Tongue weight as a share of dry weight, 13%: eighth-largest of sixteen, between the 16MRJ and 20MDS (12.7%) and the 16MKS (13.1%).
• Fresh tank, 30 gal: smallest of sixteen, level with the 16MBJ, 16MKD and four others; next are the 16MKS, 20FKDS and seven others (40 gal).
• Length, 24 ft 8 in: shared with the 19MSB; of sixteen, six shorter and eight longer, nearest the 20MDS (24 ft 3 in) and the 19BRK and 20MKB (25 ft).
• Grey tank, 30 gal: smallest of sixteen, level with the 16MBJ, 16MKD and five others; next are the 16MKS, 20MDS and three others (40 gal).

Next to the 19QRB, the nearest lighter floorplan by dry weight, the 19MBH is 316 lb heavier by dry weight, has a GVWR 1,069 lb higher, has 753 lb more cargo capacity, has a tongue weight 70 lb heavier, is 6 in longer and stands 1 in lower; the two publish the same fresh tank, grey tank and black tank.

Next to the 19MSB, the nearest heavier floorplan by dry weight, the 19MBH is 325 lb lighter by dry weight, has a GVWR 100 lb lower, has 225 lb more cargo capacity and has a tongue weight 125 lb lighter; the two publish the same length, exterior height, fresh tank, grey 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 30-gallon fresh tank is about 249 lb of water (water counts as cargo: 49 CFR 571.110 S9.3.2), 17% of the 19MBH’s 1,500 lb cargo capacity, leaving 1,251 lb. Across 16 IBEX floorplans the water share runs 14% to 36%, and 12 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).
