"quest for perfect drawer setup" - HA! So hard... and everyone's needs/priorities are different. Biggest expense in that system is probably the slides. I'd look at cost for good slides to compare DIY. The plywood is pretty cheap. That's most likely just over a full sheet of plywood (~$50), plus $50 in hardware. I would be interested to see how sturdy it is when the giant thing of water full, I have one of those and it's ~60lbs full. Plus all the other stuff, weight of the wood, etc... may sag after a while but they do have hefty slides out there so it may be fine. The part that looks like a couple shelves... anything you put in there will rattle to no end, inside a box that will surely help amplify the bass haha... it's also a lot of space and cost to primarily hold your kitchen stuff - do you use a coleman stove 100% of the time? I have a jetboil for example if it's just me. I may add a coleman stove if the rest of the fam is coming, I also have a single burner top that you screw onto a coleman bottle. All that packs up so small. Or I'll bring the tembo skottle, which I very much prefer over a basic stove (jetboil for water and such). If you presumeably add a fridge, or cooler to the other side of the cargo area you'll have almost no room left for everything else.
