Is it worth skipping the heavy duty drawer slides for a truck bed build?

I've been running a wood-on-wood drawer setup for over eighteen months now and it holds up surprisingly well if you prep the surfaces right. You don't need those five-hundred-dollar slides to get a smooth draw, even with a miter saw or a heavy compressor sitting on top. The trick isn't just using birch plywood; it's about reducing the friction points. Instead of letting the entire bottom of the drawer rub, I glued down some **UHMW plastic strips** (ultra-high-molecular-weight) on the carcass floor. It's basically like sliding your drawers on ice, and it doesn't care about sawdust. If you want to stick strictly to wood, sand the bottom of the drawers and the runner tracks down to 220 grit and rub them both down with a block of **paraffin wax** or even an old candle. It creates a slick barrier that prevents the wood fibers from grabbing each other. Since you mentioned painting it, just make sure you don't paint the actual contact points where the drawer slides. Paint on paint will get gummy and stick the second it gets warm outside, wich is exactly the headache you're trying to avoid.

Sawdust is less of an issue than you'd think. As long as you leave about an eighth of an inch of

That paraffin wax trick is a total game changer!! I'm just getting my first real shop set up and I've been stressing about those expensive slides too. If I can save that five hundred bucks, I can finally buy more clamps! Speaking of gear, I saw you mentioned a miter saw in the bed—do you think the 12-inch sliding ones are worth the extra weight if I'm mostly doing trim work, or shoud I stick with a lighter 10-inch? I'm trying to figure out if my truck can even handle all that extra plywood weight plus a massive saw!

One must also account for the inevitable dimensional instability of plywood in an unconditioned enviroment like a truck bed, where humidity fluctuations cause the drawer sides to expand against the carcass walls. To mitigate this without those exorbitant steel slides, I recommend a longitudinal 'guide rail' design—essentially a central rib on the floor—wich minimizes lateral surface contact and prevents binding when the material swells during humid months. Also, ensure you use a high-quality polyurethane glue for your joinery, as the constant vibration from the truck's suspension will eventually fatigue standard PVA glue in a heavy wood-on-wood configuration.
