It would be a lot of extra parts going into and out of your door, and really it would offer no benefits. And most big rig systems could not roll the window down far enough, there is no room under the glass for an air cylinder, unlike the bigrigs where there is a foot or more beneath the lowered glass to place and air device. Unless you dit it on a acntilever setup or a leverage setup. But is it really worth the hassle for something maybe 5 or 6 people will see.
