I bought a trucker's curtain, which I cut in half, and 3 magnetic hooks. It works pretty well. With the jumbo shade and limo-tinted side-windows, I think i will have enough privacy. I'm still debating if I will try to put a curtain behind the driver's seat (maybe the other half of the trucker's curtain).
