None of the "big" trucks I drive at work have a synchronized transmission. You can either float the gears or double clutch. As retodd7711 said most of the truck driving schools still teach to double clutch but hardly anybody touches the clutch except for starting and stopping once they leave the schools. You can ask most any driver if they float or dbl clutch and they will say float. My question is though: Why would you want to do so in your personal vehicle. It is harder to do on a synchronized transmission because you have to take into account the synchronizer working and you run for more risk of tearing something up. Just my $.02
