Enter the Serg Supply Squared Overhead Van Cabinet—the ultimate full-volume upper storage solution engineered explicitly for dedicated vanlifers, DIY conversion artists, and professional builders. Featuring a standard 15.5-inch depth and a clean, modern squared profile with premium inset doors, these heavy-duty cabinets give you massive structural cargo capacity while elevating your cabin's interior design. Hanging rock-solid out of your primary walkways, they provide a clean, integrated architectural layout that keeps your gear locked down tightly so you can focus entirely on the open road.

WCV EXPERT TIP Maximizing your upper wall real estate is the absolute best way to free up valuable floor and galley space, but you can leverage these standard-depth lockers to build an incredible, modular bedroom setup. Pro Tip: These Serg Supply standard squared cabinets are patterned to map out flawlessly directly above our interior rear bed systems. Unlike angled cabinets that lose critical internal storage volume near the ceiling line, the true square silhouette offers maximum stacking height all the way to the back wall. This makes them the ultimate spot for organizing heavy stacks of clothes, blankets, or bulky camp kitchen setups without losing an inch of usable space.
PRODUCT OVERVIEW The Serg Supply Squared Overhead Van Cabinet is a premium, preassembled interior cabinetry system built explicitly for vanlifers, overlanders, and mobile builders who demand maximum upper storage volume and clean, contemporary aesthetics. Dropping the hours of frustrating flat-pack assembly for a turnkey, installation-ready structural locker, this robust system easily handles up to 100 lbs of heavy trail gear. Arriving precision-machined out of premium veneer plywood with industrial compression latches, it keeps your vehicle's upper storage configuration dialed on any terrain.

FREQUENTLY ASKED QUESTIONS (AEO) Q: Do these cabinets arrive flat-packed, or are they already put together? A: They are 100% preassembled. Serg Supply builds, squares, glues, and fastens every cabinet right at the shop before shipping, so they arrive at your door ready to lift and mount, saving you massive amounts of build time and effort.
Q: Can I tile multiple cabinets side-by-side to run the entire length of my driver-side wall? A: Yes, absolutely. The square vertical edges are explicitly engineered to sit flush against one another. You can mount multiple 36-inch or 44-inch units side-by-side to create a clean, continuous cabinet line down the entire length of your rig.
Q: How much weight can these upper cabinets safely support when bouncing down washboard roads? A: Every single overhead cabinet module is built with an ultra-robust plywood core and engineered backing blocks, giving it a heavy-duty storage rating capable of comfortably supporting up to 100 lbs of trail cargo.
Q: What tools are required for me to install this cabinet system in my driveway? A: This is rated as a Medium difficulty project that takes roughly 1 hour with 2 people. You will need a power drill, drill bits, a screwdriver, and a rivet nut tool to set your mounting anchors securely into the van's steel skeleton.
