Just curious - is the inner tube designed with camber (crown)?
Or is it designed to be stiff and straight as an arrow? It sounds like it is meant to be a straight tube and it pivots over the wear guides like a see-saw?
Also - is the outer arm/tube really just a fixed sleeve?
…and - what are the trim tabs made of? Plastic or metal? Those are the things Lippert shows to insert the cut washer into.

Sorry to be asking so many basic questions. Just trying to get my arms around the concept so I will better understand how to watch my slides.
