Welcome to the forum Tom.
Although we don't own a Premier, I agree with MISailor... having 9 openings in a smaller trailer, airflow probably wouldn't be a problem. If need be, and for boondocking,
you could add a reversible 12-volt fan to the over-head (crank open) vent in the kitchen/dining area. There's 3-4 brands available that fit directly into the existing vent
opening & have a variety of features. Several forum members have added them & posted info in the "Modifications" section.
Hope this helps,
Terri, the Chevy co-pilot
