I assume you've thought about carpet? Curious why you haven't just done that?
Carpet just doesn't suit and easy to get burns scooting around on it. But it's certainly a possibility. I was just wanting something different. Budget hasn't been there to do it, so really haven't tried too hard to look for it.
I need to run the numbers but it seems like the case for 1/2" ply on the top is dwindling. I'll probably still run it on the bottom. if I wasn't clear, that was my planned use for the plywood.. just the top and bottom sheets. The uprights and drawers were looking like poplar like your setup.
Ah, OK. The compartments all have just the truck's carpet as the bottom in them, so are just open, no bottoms. The two drawers do have bottoms that are 3/4", but 1/2" will work.
Do your drawer slides allow the drawers to be easily removed?SNIP
I used Accuride 500 lb slides. They are overkill for the weight. I bought them extra heavy on the theory they're less likely to rattle or otherwise cause issues in an off-road application. Mine are non-disconnect:

You can spec them to disconnect, but they may be a different model number. Here's a video on how the disconnect works:

I have seen people set things up so that once the drawer is slid out, then the kitchen unfolds from it if you want to leave everything attached.

Some folks don't use slides at all, instead using strips of UHMW. The drawer comes right out if done that way and no fiddling with disconnects. The problem is opening them on the trails, where things might just not be level when you need to get at something most. Hate to drop the tailgate and have your drawers slide out onto the dirt at some extreme angle, but maybe there's enough friction that won't happen?
For us, we slide the fridge back onto the tailgate, then crawl past it on the other half of the tailgate to get in and out most of the time, as that's easier than using the side doors for an old fart like me. We have a drop-in board that fills the space it takes when it's in forward, travel position. The space that is down there makes for a little leg room if forced by weather to stay inside, plus room to stuff boots, overcoats, etc for overnight where it's out of the way.
