You don't give the year of your truck, but if you have a manual choke and are used to an automatic choke or fuel injection, you may have trouble getting used to it. I give the engine full choke and pull the throttle out far enough to keep the revs up on the first start on a cold morning and immediately push the choke all the way in so as not to wash down the cylinder walls. I do use the choke as needed to prevent bucking when going through the gears with a cold engine, so I look a little busy shifting then pulling the choke out, accelerating, pushing choke in, giving arm signal, shifting, pulling choke out, etc, until the engine warms up.
