By unit do you mean the set, or the acting/direction, or both? I mean I saw in the 90s a bus and truck (VERY bus and truck) tour of Guys and Dolls that was based on the Jerry Zaks revival (looking at the program apparently they had the costumes from a past larger tour that was I'm sure more faithful to the Broadway design). The sets were literally basic flats/backdrops with nothing else there, and I ws prett worried wqhen I saw how threadbare it was. But the cast and energy actually made up for it and it was one of my more surprising theatre experiences (surprising in a good way, that is...)
