Strangely enough, Forest River makes the Ibex, GeoPro, and No Boundaries lines all at once - they all share many of the same parts, with a few variations (mostly in the nose and in how the rear area is partitioned - e.g. the NoBo has a closet in the rear dry bath, while Ibex has it next to that rear dry bath as a separate space.)
