Lookin for Utility rear storage platform ideas

Looking for ideas of a DIY finished storage platform set up for the rear area behind the seats in a utility 3rd Gen. Have seen the goose gear and have used the search function but don’t wanna pay $7-1000 for the platform. Any one have plans with measurements for DIY verison?

I’d use his design and modify it - the T-Nutz extruded aluminum bar frames makes it super easy to work with. You can also cut them to length with a regular Miter saw and drilling it is easy.

Screenshots of his plans- the lengths should be the same, just play with the width and heights…
