Good point Bill. I got a reply elsewhere from a 2021 2600RB owner that said he has the same issue and that his dealer was unable to rectify it. He said he just puts a doorstop rubber wedge under the slide at the sagging point for travel then removes it when extending the slide. You are right that the composite floor is not stiff enough. Even on the new Model 2600RBs it is wobbly.
