The Slate's 5-foot bed comes bare, but it's built to organize: T-rails, factory bolt points, and the largest accessory section in Slate's catalog. The MOLLE Paneling Kit is $214.99 and mounts to the extruded rails with T-slot hardware, no drilling. Toppers are inflatable — $1,449 for the CAP, $1,599 for the Mid-Rise — and toolboxes run $599.99 either style.
What you’re working with: the Slate bed
The Slate’s bed is 5 feet long with T-rails and factory bolt points designed for accessories from day one [VERIFY exact dimensions against slate.auto]. Unlike most trucks, where storage systems fight the bed design, the Slate was engineered assuming you’d bolt things to it.
Two numbers to keep in mind before you buy anything: 1,550 lb of payload and what’s left of it after your gear. Every storage system, box, and rack spends from that budget — the payload math guide works through a real build.
Truck Bed Accessories is the single largest section in Slate’s catalog. That’s not an accident of merchandising; it’s the clearest statement of what this truck is for.
The MOLLE panel system
Bedside MOLLE panels turn the dead vertical space above your wheel wells into organized, secure mounting real estate — pouches, tools, traction boards, fire extinguishers, Rotopax, all off the bed floor and exactly where you left them.
The BuiltRight kit is the most established option, and the only one co-developed with Slate’s team. It mounts to the truck’s extruded rails with T-slot hardware at two locations per panel — no drilling, hand tools only — and panels run individually or gang together into one continuous surface using the connector pieces included in the kit. It carries BuiltRight’s block-and-slot pattern: standard MOLLE spacing plus horizontal slots that take clamps, brackets, and mounts that plain MOLLE grids can’t. Made in USA, lifetime warranty. It’s sold directly in the Slate accessory configurator.
The install guide is here — around 20–30 minutes with basic hand tools [VERIFY].

Two things worth pointing out in that table. First, the 3-piece pouch set at $105.00 is not obviously a discount: a small pouch is $32.00 and a large is $43.00, so what the set contains determines whether it saves money. Slate doesn’t itemise the mix. If you know which sizes you want, price them individually and compare rather than assuming the bundle wins.
Second, the Paneling Kit and the Attachment Essentials Kit are different purchases. Panels give you the mounting surface; the essentials kit gives you the hardware to hang things on it. Together that’s $442.98, which is the realistic number for a working MOLLE wall rather than the $214.99 headline.
Where to start
If you buy one thing: the MOLLE Paneling Kit at $214.99. It’s the structural piece everything else attaches to, it’s a Moderate install with hand tools, and the panel surface is useful before you’ve bought a single pouch. Add attachments as you discover what you actually carry, not in advance.
If you buy nothing: MOLLE spacing is a published standard, and Slate has released CAD files. Printed and fabricated attachments work alongside commercial panels. Buy the structural stuff, print the small stuff.
Toppers: the inflatable ones
Slate’s toppers are inflatable, which is genuinely unusual and worth understanding before you order one.
| Topper | Price | Install |
|---|---|---|
| Air-Topper CAP | $1,449.00 | Beginner |
| Air-Topper Mid-Rise | $1,599.00 | Beginner |
A conventional truck topper is a rigid fiberglass or aluminum shell that clamps to the bed rails, weighs well over a hundred pounds, needs two people and usually a shop to fit, and lives in your garage the rest of the year. Slate’s Air-Toppers are inflatable structures instead. That’s why both are rated Beginner install — the lowest of Slate’s four tiers, the same tier as a floor mat.
The honest trade-offs, stated plainly:
- In favour: dramatically lighter, which matters against a 1,550 lb payload ceiling. Removable and packable, so a topper isn’t a year-round commitment. No shop visit, no lifting a shell off a truck by yourself.
- Against, or at least unknown: Slate has not published inflated dimensions, load ratings, weather or wind performance, puncture resistance, or the pump arrangement. An inflatable structure and a fiberglass cap are not equivalent products, and anyone telling you how a Slate Air-Topper handles a highway crosswind is guessing — nobody has taken delivery yet.
[VERIFY Air-Topper dimensions, weight, and load rating against slate.auto]
Mid-Rise vs CAP: $150 separates them, and the names imply the Mid-Rise sits taller. Slate publishes no height figure for either, so we can’t tell you how much taller or what it buys you. That’s a real gap in a $1,449-to-$1,599 decision.
Slate sells a related family of inflatables — the Air-Deck at $549.00, the Air-Carrier Medium at $519.00, and an Air-Storage at $299.00 in the roof rack section — which suggests inflatable structures are a deliberate platform choice rather than a one-off.
Toolboxes and bed floors
| Item | Price | Install |
|---|---|---|
| Crossover Toolbox | $599.99 | Moderate |
| Gull Wing Toolbox | $599.99 | Moderate |
| BedBoss Lite Structural Floor | $749.99 | Advanced |
| Truck Bed Organizer Slide Out Mat | $229.99 | Beginner |
| Truck Bed Mat | $119.99 | Beginner |
The two toolboxes are the same price, so the decision is purely about how you want to open it. A crossover box spans the bed behind the cab and opens from either side; a gull-wing opens upward in two halves. Neither costs more, which is a refreshingly clean choice.
Both spend payload and both spend bed length on a bed that only has five feet of it. On a short bed, a crossover box is a bigger proportional sacrifice than it is on a full-size truck — worth measuring what’s left before you commit.
The BedBoss Lite Structural Floor at $749.99 is the most expensive non-topper item in the section and the least documented. “Structural floor” implies a load-bearing platform, the Advanced install rating implies real mounting work, and that is the end of what Slate publishes. No load rating, no height, no description of how it attaches. We’re not going to infer a use case for a $749.99 part.
T-rails, tie-downs and the rest of the bed
| Item | Price | Install |
|---|---|---|
| Truck Bed T-Rail Crossbars | $249.99 | Moderate |
| Truck Bed T-Rail Kit, Top | $124.99 | Moderate |
| Truck Bed T-Rail Kit, Inner | $124.99 | Beginner |
| Truck Bed T-Rail, Partition | $74.99 | Beginner |
| Basecamp 3.0 Tailgate Pad, Mid Size | $369.99 | Beginner |
| Tailgate Lock Kit | $100.00 | Moderate |
| Cargo Net, Mid Size | $99.99 | Beginner |
| Skid Plate, Mid Size | $59.99 | Beginner |
| MedKit | $99.99 | Beginner |
The T-rail kits are the quiet enabler here. They extend the factory rail system to more of the bed, which means more places to clamp, tie, and partition — and the community is already adapting third-party clamps, phone mounts, and cup holders to the same profile. At $124.99 a kit they’re among the highest-leverage things you can add.
Tonneau covers
Bed covers are their own decision, and Slate’s lineup runs from a $1,000 tri-fold to a $2,299 folding solar panel. Because the solar version raises a completely separate question — whether a bed-sized panel does anything meaningful for a 205-mile truck — we do that math properly on the Slate truck solar page, including why the SOLIS + COR bundle costs $349 more than buying the parts separately.
Short version if you just want a cover: the Tri-fold at $1,000.00 and the NEXUS Flip-Up Hard Tonneau at $1,349.00 are the non-solar options, and for most owners a conventional cover plus a home wall charger is the better use of the same money.
The DIY corner
Slate released CAD files and 3D-printable “Slatelet” accessories, and the maker community is active. If you print or fabricate your own attachments, MOLLE-spec spacing means they’ll work alongside commercial panels. We’re pro-DIY here — buy the structural stuff, print the small stuff.
