We have a 2015 CC with the double pained Hehr windows. I just looked at ours, as we are camping this week, and you are right. The bottom up windows have weep holes and the crank out ones do not. Our double pain windows do not/have not had any condensation in the 8 months we have had it. Last two days were rainy with temps in the low 50's during the day and 30's at night. I do keep the vents in the kitchen and bathroom open, with covers over the vents. But no condensation. Not sure how the non-weep hole windows are supposed to drain the condensation out of the RV. Seems like a design issue.
