A waste in one aspect, loading / space if you’re carrying sand, but think of this scenario:
You’re going on a 4x4 trip where you move each day. You need to stop on the side of the road and eat lunch etc.
You have a load of camping equipment, bedding, camp chairs etc all lying in the bak on top of the ammo boxes or crates of food or whatever because you’re usually hungover and late so you chuck stuff in.
Now, when you stop to eat, you need to unpack some larger items to get access to the boxes, yes you can pack cleverly, but a drawer system with a solid top just makes everything so much more accessible and neatly packed that it proves it’s worth. All your crap can be loaded on top and the food and drinks etc are protected and available whenever you need it.
I had a very simple slide out drawer for my Coleman and another for food and kitchen crap in my SWB Paj on the river trips and they made life so easy.
For a bakkie builder like Manny, a drawer system is a waste
