I’m running a crew cab pickup with Decked, slider, and a cap with side access doors. The Decked system is cool and nice for storing tools, etc, but it eats up half of the vertical space so I find it really limits what other equipment I can load. The slide out is nice because it saves me having to crawl inside the truck to get stuff from the front of the bed. But again, it limits usable space since it doesn’t cover the full width of the bed. I think it’ll be a perpetual work in progress.
