I am getting the feeling it has no use at all...We drive our burb about 100 km/h all the time (about allmost 60 mph) and it rains a lot here in the netherlands and even in heavy rain I dont see the water moving down the back window, it just seems to sit there. but then agai I have no reference, but would love to take it off...I think it looks strange on our Burb on the back
i had one on the 88,with barn doors
sure seemed to help clear the back better then the 87 without
i took it off now, for the Jimmy,it helps keep the exhaust out too
you could remove the top half see if it helps/works even less
but may need to angle it more ....
don't have many pics of it
