2026 Forest River IBEX19QRB

The IBEX 19QRB has 747 lbs of cargo capacity between 4,168 lbs dry and its 4,915 lbs GVWR, 15% 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 515 lbs, 12% 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 5th of 16 floorplans by dry weight, in a line that runs from 3,778 lbs to 6,733 lbs. It sits in the lighter third of the line.

Plan the tow on loaded weight, not the 4,168 lbs dry figure: half the published cargo capacity brings this plan to about 4,542 lbs, and the published GVWR of 4,915 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 19QRB is a feature-rich, tow-friendly travel trailer that blends comfort, function, and durability. A front queen bed provides a cozy retreat with ample storage, while the central kitchen, complete with a large fridge and air fryer microwave to make meal prepping effortless. The slide-out sofa adds spacious comfort for relaxing or entertaining, and the rear bath features an upgraded shower and high-power fan.…” 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 19QRB differs from the other fifteen IBEX floorplans. Most distinctive first. How these ranks are worked out.

Next to the 16MBJ, the nearest lighter floorplan by dry weight, the 19QRB is 80 lb heavier by dry weight, has a GVWR 670 lb lower, has 750 lb less cargo capacity, has a tongue weight 30 lb heavier and is 2 ft 6 in longer; the two publish the same exterior height, fresh tank, grey tank and black tank.

Next to the 19MBH, the nearest heavier floorplan by dry weight, the 19QRB is 316 lb lighter by dry weight, has a GVWR 1,069 lb lower, has 753 lb less cargo capacity, has a tongue weight 70 lb lighter, is 6 in shorter and stands 1 in taller; the two publish the same 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), 33% of the 19QRB’s 747 lb cargo capacity, leaving 498 lb. Across 16 IBEX floorplans the water share runs 14% to 36%, and 1 gives up more than this one. Nearest on that share: IBEX 23MBH at 22% and IBEX 16MKS at 36%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.110 S9.3.3).
