Door and truck stripping

From the pictures it does not appear that there is a problem with the window gasket. It is not uncommon to have a gap show in this area between the trim and the a-pillar. Water can always easily flow under the chrome trim when done properly. You problem is more likely in the bottom corner of the window, where there may be a rust hole allowing water to enter the car and drip exactly where it is on your floor.
