Sliding rear window.

I've added a new item for my wish list:

After last winter rear window corners rust problems  I had rear window installed with dark film to reduce sunlight to entering the cabin, but at the moment I didn't thought it really through. As we are participating at cruises like Iso LänsiUusimaa Cruise, I shoot as we drive in both directions, forward and backward. And when I shoot backwards I either hang out from the window or shoot straight through rear window so that I can get shots like these:

Now I have tinted rear window and the problem is that shutter times are slower due reduced light coming through that film. Then I remembered that I saw somewhere over the internet a sliding rear window for 1968-1972 El Camino. I did a search and I found this:

Sliding rear window:

"Product Description
* Specially Built for Classic Older Trucks
* Original Four-Panel Design Gives the Widest Possible Opening
* Fully Contoured Powder-Coated Aluminum Frame with Narrow Stiles and Tight-Sealing Weatherstrip.

The CRL Oldie Truck Slider is built to the same quality specifications as our Duo-Vent, the finest four-panel Truck Slider on the market. It's our attention to the details that makes the Oldie Slider so special. The state-of-the-art fully contoured, thin profile, powder-coated aluminum frames have narrow stiles for maximum rear view, and tight-sealing weatherstrips to protect the interior. Tempered safety glass and metal locking latches for cab security are features that make CRL Sliders stand out from any others."

So, with that I don't have a problem with reduced shutter times and no problems with reflections from the window as there is a opening where I can shoot! Plus strategically placing cooler at the front of the bed I can grab a cold beer!
