Slate's official frunk lineup is three items: Frunk Cargo Hooks at $29.99, an All-Weather Floor Liner at $49.99, and a Carpet Floor Mat at $49.99. All are Beginner installs and the whole set totals under $130. There is no official frunk organizer, divider, or lockable box, so organization is where generic and DIY solutions win.
How big is the Slate truck frunk?
7 cubic feet. That figure comes from the dimension diagram on Slate’s specs page, read August 10, 2026 — and it is a correction to an earlier version of this page, which said Slate had not published one. It had; we had been reading the spec-sheet PDF rather than the diagram on the live page.
For scale, 7 cu ft is roughly a large airline carry-on plus a grocery run, or a 45-quart cooler with room around it. It is a genuinely useful space rather than a token cubby.
What Slate still has not published is the shape — the opening dimensions, the floor area, and the depth at the shallowest point [VERIFY frunk interior dimensions against slate.auto]. On a frunk that matters more than the headline volume, because an awkward 7 cu ft and a square 7 cu ft hold very different things. Any specific opening dimensions circulating on forums still trace back to somebody eyeballing a press photo.
What you can do is know exactly what to measure the day the truck lands, because four unknowns decide what the frunk is actually good for:
| What to check | Why it changes your plan |
|---|---|
| Opening size vs. floor size | A big floor behind a small mouth means no rigid crates — soft bags only |
| Depth at the shallowest point | Determines whether a cooler or tote stands up or has to lie down |
| Is it drained? [VERIFY] | A drain plug means you can hose it out and haul wet gear; no drain means liner-only |
| Does it lock with the truck? [VERIFY] | Decides whether it’s secure storage or just covered storage |
| Is there a 12V outlet? [VERIFY] | Powers a plug-in cooler; without it, the frunk is passive space |
None of those are answered in the published spec material, and all four are worth confirming before you spend money on anything shaped to fit.
We’ll publish real numbers here as soon as they exist. Whichever comes first — Slate publishing a frunk spec, or measurements taken off a delivered truck — this page gets the actual volume, dimensions, and answers to the four questions above. Until then the blanks stay blanks.
What frunk accessories does Slate actually sell?
Three items, all filed under Interior > Utility, all Beginner installs, and the whole lineup totals under $130.
| Item | Price | Install | Best for |
|---|---|---|---|
| Frunk Cargo Hooks | $29.99 | Beginner | Keeping bags upright and stopping slide |
| All-Weather Floor Liner | Frunk | $49.99 | Beginner | Wet, dirty, or greasy cargo |
| Carpet Floor Mat | Frunk | $49.99 | Beginner | Clean storage, quieter, better looking |
Prices from the Slate configurator, captured July 6 2026 and re-verified unchanged on August 10 2026 — re-check the accessory price database before ordering, since the catalog is still moving.
That’s it. No organizer, no divider set, no frunk box, no lockable insert, no cooler. For a truck whose whole pitch is modularity, the front trunk is the least-developed corner of the official catalog — soft goods and hooks, nothing structural.
Cargo hooks are the best $30 in the lineup
If you buy one frunk item, buy the $29.99 hooks. A frunk is a smooth tub, and a smooth tub turns every grocery run into a game of retrieving a rolled bag from a corner. Hooks are what convert that tub into something that holds bags upright and keeps a bungee or cargo net anchored — the cheapest meaningful upgrade in the whole Interior > Utility section.
The liners are worth having, but they solve cleanup. The hooks solve the actual functional problem, which is that nothing in an empty frunk stays where you put it.
All-weather liner vs. carpet mat: which one?
Both are $49.99, so price is not the tiebreaker — pick on what you’ll carry.
| All-Weather Liner | Frunk ($49.99) | Carpet Floor Mat | Frunk ($49.99) | |
|---|---|---|
| Best for | Charging cables, recovery gear, muddy boots, wet coolers | Groceries, luggage, tools in cases, camera bags |
| Cleanup | Wipe or hose (if the frunk drains) [VERIFY] | Vacuum |
| Noise | Rubber can drum a little | Deadens rattle |
| Buy this if | The frunk is your dirty-work locker | The frunk is your clean second trunk |
Our lean for most owners is the all-weather liner, for one reason specific to this truck: your charging cable is going to live up there, and cables come home wet, gritty, and covered in whatever the charging bay floor had on it. Carpet is the right answer only if you’ve already decided the frunk is the clean space and the bed handles the mess.
Building out the front and rear of the truck together? Price the whole list in the accessory database. The frunk lineup totals under $130 — it’s the cheapest corner of the truck to finish, and the easiest to overbuy for.
The organization gap — and the cheap answers that fill it
Storage and organization is the community’s most-requested mod class, and the frunk currently has almost nothing official to offer it, which makes this the one area where generic and DIY solutions are genuinely the right call.
Nobody should pay a premium for a branded frunk divider that doesn’t exist. What actually works:
- A collapsible trunk tote or milk crate. $15–$30 anywhere. Contains the load, lifts out in one motion, and doesn’t care about dimensions being unpublished — you buy it after you measure.
- A soft-sided cooler. Fits irregular spaces better than a hard cooler and won’t rattle against composite panels.
- A cargo net or bungees run to the hooks. The hooks are only worth $29.99 if you actually anchor something to them.
- 3D-printed dividers and trays. Slate has leaned into an open, hackable platform and there’s an active print-and-fabricate crowd forming around it; whether official CAD files cover the frunk cavity specifically is not something we can confirm yet [VERIFY CAD/print-file availability for the frunk]. If you print, print to your own measurements, not to a forum post’s.
We’d rather tell you to buy a $20 tote than pretend there’s a $200 answer. When a purpose-built frunk product is worth recommending, we’ll say so here.
Why the frunk matters more on this truck
Because the bed is open and five feet long, the frunk is the only enclosed, weather-shielded, out-of-sight storage the truck has.
That’s a different job than a frunk does on a car. On a Slate, the split is clean: the bed is for volume and dirty freight, handled by the bed storage and MOLLE ecosystem; the frunk is for the things you don’t want visible from a parking lot or soaked in a rainstorm. In practice that means the charging cable and adapters — see the Slate charging guide for how much cable you’re actually storing — plus recovery gear, a first-aid kit, jumper cables, and the tools you’d rather not have loose in the cabin.
For the cabin side of that same problem — console, cubbies, and the T-rail system — see interior mods, the sibling to this page.
One caution: frunk cargo isn’t free weight. It counts against the 1,550 lb payload like anything else, and it loads the front axle specifically, so a heavy frunk plus a heavy bed is worth checking against the payload math.
Start with the hooks, add the liner that matches your mess, and fill the rest with something cheap and generic until the aftermarket catches up. For the cabin side of the same problem, interior mods is the sibling page.
