Just to update this post, we went with the Ventline VP 543 here, http://amzn.to/1IMkkJ7 . Installing was fairly simple, I'm currently working on house battery with solar panel ideas so I don't have a review just yet. I'll swing back round once we've put it through its paces.
I REALLY want to hear about your experiences with this fan. It's been in my cart on Amazon for months. I want to install in my Suburban but I've been holding off pending more research.
