Great looking build, what I would do is Add the berrings or wheels to the underside of the drawer as well to help even the wear on the 2x6 and keep the weight to a minimum vs adding the plywood to the bottom.

The “best” is a pretty bold statement, sir.

Another thought is you could add 1/8" thick metal strips on the top and bottom edge of your 2x6?

How did you build this?
