I think I am the only Jeep Liberty owner who does not care for the Skyslider. I had read some post about air and water leaks which was enough to keep me away. I also did not like the idea of a wide open ejection port in the event of a roll over. Nor any loss in structural strength.
I do have the power sunroof on my 2011 KK. Not because I wanted it, but because it was there and the selection of 70th Anniversary Editions was pretty slim. I do pull the shade back to let the sun shine in. I have been know to pop it up for ventilation. I have even run with it open a time or two, but it also comes with some noise increase.
The power sunroof does offer three different position, closed, pop open for vent, or full open. Or closed but the interior side pulled back for a view with not having to open the roof.
The skyslider offers a full open view and wind experiance or closed with wind noise. It also pretty much deletes any real application of a useable roof rack system.
Either way you go, you'll have a Liberty and that is the best part of all choices.
