Vehicles are bought and sold on longer time horizons than the shortage, diesel pickups were always somewhat of a rounding error and they kinda fell out of fashion hard about 5yr ago when emissions components got bad/numerous enough that the TCO didn't pencil out vs gas trucks. The OEMs saw this (the emissions driven increased TCO of diesel, not the shortage) coming ~10yr ago rolled out a new generation of gas engines for pickups, vas and MDTs which hit market in the last couple years so if anything this will drive a faster transition back to gasoline engines in those applications.
