It took a few months in total, thanks partly to delays in other portions of the build, but I finished up my sliding trays a couple of months ago. They came in handy for my 2.5 week trip last month!
The drawer slides I used are 48" heavy-duty slides made by Fulterer. They offer many lengths in two-inch increments. www.cabinetparts.com/p/fulter...

(This is the second video I've done using DaVinci Resolve. I'm digging that editing program! Much more flexible than iMovie. There's a learning curve to be sure, but it's worth the time.)
