Exactly, Tag, none of this is new. A CHORUS LINE (surprisingly more complicated than it looked from the house because Michael Bennett demanded the original Broadway set--built for a long, long run--be duplicated at each stop) did so in the 1970s, as did EVITA, IIRC.
Bottom line: if you are the Show of the Decade (ACL, PHANTOM, HAMILTON, etc.), you can afford to build two sets (or partial sets) and jump them during the early national tours.
Less successful Broadway shows, and later bus-and-trucks of even the biggest hits, are scaled down to be struck, trucked, and set up again in a day or two. Hence, ROBBER BRIDEGROOM (1977-8) toured the upper Midwest in winter, with a single set, which I'm told didn't always get put up in time for an opening. SWEENEY TODD left the "foundry" behind when it went on the road.
