Jalousie windows vs. sliding windows - Pros & Cons

Prefer the duel panes and they are slider only.

For ventilation in the rain (we are in the PNW so we know all about rain) the vent covers on the overhead vents (and fans) combined with the pass through window to the truck provide excellent air flow and can be left open all of the time.

When fully open the sliders also give more area for air flow. They can also be opened in the rain but, as noted, only if there is no wind.
