For years I've been considering how to make the back windows on my van
open, so that my dog can get her head out and sniff the air.

I've seen a few interesting options.

I'm thinking about taking out the slidingdoor window, and it's counterpart
on the driver's side, and flipping them. That way the open window would be
accesible from the back bench. The dog could put her paws on fold out
table, and get some air.

The passenger side silding window has the danger of a guillotine effect
when the door opens, but a mostion limiter would take care of that.

Any thoughts? Anyone seen this, or even considered it?
