My own drawings were rudimentary.
I got my inspiration from a Dutch forum member who had a webpage In English devoted to their build. However I have just checked the page and in the last month it appears the domain has expired. This is the link in case they renew it:

I’m sorry I can’t recall which member it was.
Essentially, I bought about 5m of 50x50mm aluminium angle and a couple of metres of 50mm flat bar from Aluminium Warehouse:

These drawer slides, I think 850mm, from Amazon:

And rather than go hunting for specialist T bolts, I used M8 threaded dowels and threaded rod to make the securing bolts to the van’s rails.
Fabricate the tray out of angle with a simple overlapping joint pop riveted together. Then make an open-ended frame wider than the box and secure its open width with the flat bar to provide support across the open end and to supply a fourth hold down point. The frame has to be 38mm wider internally than the tray. I used 13mm ply for the base.
I made mine wide enough to take 2 x 600x400 and 2 400x300 Eurocrates. They fit snugly in the tray.
At the dimensions I made the tray the bench seat has to be about 5cm further forward than its usual position. this has had no adverse effect on our set up, but others made need that space.
All in all, it works beautifully and is not beyond the average DIYer’s ability. It has vastly improved our arrival and departure experiences on sites and generally made everything more accessible. Another benefit I hadn’t considered but has become apparent is that you don’t have to put anything down on wet grass to access what’s behind or below it anymore, thereby keeping the boot and its contents cleaner.
The finished product minus a couple of 600x400 crates in the front corner:
