dude your in a really cold state , your truck should smoke when its really cold for about 15 min or till your truck hits 120º or so. im from cali i never seen my truck smoke till i moved to washington, now it smokes till its warmed up... the res for the coolant will rise above max when the truck hits 196º but lately its been super cold and its near the min in the coolant tank.. inspect your heads and if it doesnt smoke when its all warmed then dont worry bout it..
