I'm not familiar with your camper, but the post above about the fantastic fan,.. it can really suck. A few weeks ago we had it on in our pop-up, but my wife closed the canvas vent over the bed cause she was cold. I got up and I was wondering why the vinyl windows were bulging inward,... nearly 1 1/2 inches! I could press on them like a bubble. I opened the camper door to go outside and see and WHOOSH! the air flew in!
That fantastic fan created such a negative pressure it was sucking in on the sides of the canvas!
