DIY Window Idea

This is for a door window as it is a slider. An awning window would hit the body of the camper when open. The window is a vertical slider, 15x12 tempered glass.
The glass is a cutting board bought for $6.
The frame/channel is an aluminum J moulding for house siding. I have used the J channel for small, inexpensive gutter on the camper.
Notch 90° out of the J in three spots so the glass fits securely inside the frame but still glides without binding. Make the frame large enough so the glass can drop down to open.
Measure the door opening by holding the frame in place and marking inside. Be sure not to cut the opening too low because the glass needs to cover the opening.
Position the frame with the glass inside on the door. Attach the frame.
Use a ribbon for the open/close mechanism. Attach the ribbon to the top of the frame. Drop it over the front of the glass and under the bottom of the glass. The ribbon is then inside the door. Raise the glass by pulling on the ribbon. Drop the glass by releasing the ribbon.
I am trying to get my mind around this idea so thought I would float it past everyone.
