Beanik,
From the looks of it, and considering that it will be pushed back due to one less row, the only way stuff might not fly out is through the webbing being flush with the roof height of the front half of the cabin. This is by no means a reliable way of keeping stuff in, but as long as there is not too much sag and the webbing lines up well enough with the front roof, it would help a little. Myself...I wouldn't put anything too heavy in there, unless you want it stuck in the the back of your head.

Ian, you've seen this up close and personal...any details on this?
