I agree with the others... it's simply a new floorplan being added to the existing line-up & that's not
typically a cause for major concern.
Floorplans are commonly added (or deleted) for the new model year, and those of similar size will have
common denominators in the build design, so... it's unlikely that the 23RB will be completely
unfamiliar to the factory workers. It's possible that same (or nearly identical) floorplan may already
exist, or did exist, in another Keystone brand.
There were '7' Passport floorplans added for 2012 which included an entire 'new' line of 5th wheels.
Maybe one of our members has one of those '7', and can also offer some first-hand insight.
