Remove double bunk w900 areocab

Hey guys I was wondering if anybody her has taken out or knows how to take the second bunk out of an areocab kenworth do they just slide out the emergency exit window holes? Or is there some other secret to getting them out.

I've got a leak in the bunk somewhere on the right side an was gonna gut it to find the leak an also clean behind the panels cause right now it leaving white water trails on the leather so I can just imagine what behind looks like. So anyway I want the bunk outta the way cause it looks like it'll be a pain to work around

Thanks guys
