Looking back at the OP, the thing that really comes to mind is the lack of space for removed hive parts.
I often have another stand adjacent, or a spare box, for standing boxes on as they are removed. Empty boxes are easy enough early in the season - just park them on the up-turned roof, but removing a couple or three fairly full supers and parking them at or near ground level, is ergonomic rubbish! Little wonder beeks often suffer with bad backs!
I would think that many who have 'double' hive stands really have 'triples' but use that 'third' space for parts during inspections?
