Condensation forming on top of the dash

[Bigbear1971]

I just bought a 2016 Silverado crew cab on 7-2-2016 and about 6 or 7 times of the morning the dash starts to get condensation on top of the dash above the right side vent and this morning it got wet all over the top of the dash dealer said everything was fine but everyone else I have talked to said this is not normal at all any body have any ideas on the problem
