I doubt a 23% reduction across the board is possible. Dump trucks,Cement mixers,log trucks and Heavy equipment haulers will always use more fuel. Bad aero, heavy loads and short hauls on secondary roads with lots of stops, just eats fuel.

Also, open flat bed trailers with their constantly changing load configurations.
