Back window
 

Any chance of damaging the back window in the up position while running a killertoytop? My concern is the lack of structural support and normal road vibration.

yes, there is.

That would be why there are fail safes in place, so you can only operate your window with a hard top bolted down properly. Otherwise, like you said, there's no structural support around the top and sides.

That is what I was thinking. I'll get the back window attachment and save the back glass for the hard top days.

while I agree that there is a chance to damage the window, KTT is a pretty reputable company with more than a few satisfied customers. I think if the design was that bad, they wouldn't run it.

Yes they are a great company, and I already have the soft top. It is a great top, but I'm still concerned about the vibration over the long term. I called them and a vinyl window is on the way.
Thank you.
