Just verified that Build Sheets are generated AFTER the truck is built. My order is currently at the body vendor and BS popped this morning.That's a good question. I'm not 100% sure of this, but I believe the build sheets are generated (internally) when the vehicle BEGINS production. We typically see it posted the following business day, which usually coincides with the vehicle having been partially (or completely) produced. Then it goes to the body vendor, if necessary.
