Like dstankov said, Vegas and Axis have a sliding window on both sides of the front seats. There is a latch to lock the two sections together. The rear section slides forward, and you can slide the screen after the window is opened.
Some folks always leave the driver side window unlatched, just in case the door latch breaks like ours did earlier this month. There are a couple of running threads on that, search for "Trimark".
BTW, did you download Ed Felker's excellent crowd-sourced manual for Vegas/Axis? Find it in a sticky under Motorhome Tech Topics. It tells you all the things that the Thor manual left out, and more!
I think we need to stop calling it "working from home" and start calling it "living at work!"
