In over the hill, “inventory” means the tool slots on one vehicle. Every vehicle starts with one slot; the Mechanic sells three upgrades that raise capacity to two, three, and finally four slots for 25, 50, and 75 pebbles. The complete tool-slot line costs 150 pebbles, and four slots is the hard maximum.
These are per-vehicle upgrades, not garage-wide unlocks. The figures below come from the 14 October 2026 Steam release build as documented by the unofficial overthehill.app upgrade table; patches released later in October were not accompanied by a republished price table.

What does “inventory” mean in over the hill?
The game uses inventory to describe how many equipment items a vehicle can carry at once. It is not a backpack with a growing list of discoveries: the relevant upgrade is called Tool Slot 2, Tool Slot 3, and Tool Slot 4 in the upgrade data. A stock vehicle has one tool slot, and the final stage leaves it with four.
All seven tool types are already available from the beginning. Pebbles buy carrying capacity, not new tool categories. The tools are selected for the current vehicle at the Mechanic, then consumed or retained according to each item’s rules. A different truck keeps its own capacity and loadout.

How many tool slots can you get?
Four slots per vehicle is the maximum. The published upgrade table contains no Tool Slot 5. The ladder is:
| Stage | Cost | Requirement | Capacity after purchase |
|---|---|---|---|
| Stock | Free | None | 1 slot |
| Tool Slot 2 | 25 pebbles | None | 2 slots |
| Tool Slot 3 | 50 pebbles | Tool Slot 2 on that vehicle | 3 slots |
| Tool Slot 4 | 75 pebbles | Tool Slot 3 on that vehicle | 4 slots |
Total to reach four slots: 150 pebbles — overthehill.app, 2026. The 25-, 50-, and 75-pebble figures are launch-build data read from the game files and corroborated by a same-month upgrade reference, rather than prices printed on the Steam store page.
How do you buy the upgrades?
The upgrades are purchased from Crazy Günther, the roaming mechanic. Some guides spell the name “Crazy Gunther,” but the launch review by The Wand Report uses the accented spelling. His van appears at a designated location on each map and also functions as a fast-travel point.
- Drive to Günther’s van. The mechanic is the vendor for vehicle upgrades and equipment changes.
- Select the vehicle you want to improve. Capacity belongs to the selected truck; buying it on one truck does not affect another.
- Buy Tool Slot 2 first. Tool Slot 3 is locked until the second slot has been purchased on that same vehicle, and Tool Slot 4 similarly requires Tool Slot 3.
- Choose your equipment. The extra space changes how many items you carry, not which tool types exist.
- Return to the mechanic, a cabin, or a cabin respawn when you need a refill. Empty slots refill at those locations.
Once a stage is owned, it can be removed and re-equipped at no charge. That lets you change a truck’s configuration for a different trail without paying the 25/50/75-pebble cost again.
Can tool-slot upgrades be shared between vehicles?
No. Each truck has its own upgrade state. The game starts you in The Protector, with The Ding and The Trailrat already in the garage; other vehicles are earned by completing challenge trails. If you buy all three capacity stages on The Trailrat, a newly unlocked vehicle still has its original one-slot capacity until you upgrade it.
There are 21 vehicles in total. A four-slot package costs 150 pebbles per vehicle, so upgrading every truck’s capacity would require 3,150 pebbles (150 × 21). That is a calculated total from the published per-vehicle price and vehicle count, not a separate in-game price.

What tools can the four slots hold?
The tools page lists seven types, but ownership limits mean you cannot carry one of every type at once. The table below gives the maximum copies available to the player, not a per-slot upgrade level.
| Tool | Maximum owned | What it does |
|---|---|---|
| Repair kit | 3 | Restores a vehicle, or a teammate within 20 m, to full health. |
| Portable winch | 3 | Creates a temporary anchor where there is no natural hook point. |
| Jack | 1 | Flips an overturned vehicle and moves it up to about 7.5 m. |
| Planks | 3 | Places two 8 m planks for gaps, ditches, or poor traction. |
| Camp tool | 1 | Skips 12 in-game hours in roughly 44 seconds and repairs 25 health on every vehicle in the session. |
| Meteorite radar | 3 | Points toward the nearest meteorite that has already landed. |
| Cloud Clearing Bell | 1 | Clears bad weather for everyone for a limited time. |
That is 15 individual items across seven types, while a vehicle can carry at most four. The widest stack is three (repair kits, portable winches, planks, or radars), so even a stack-heavy loadout leaves one slot unused. The jack, camp tool, and bell cannot be duplicated because only one of each is owned.
Using an item does not always consume it at the moment you press the button. The jack, portable winch, planks, and camp tool are spent when placement or activation is confirmed. If the action is cancelled before confirmation, the item remains available. The tools reference also notes that a radar is not consumed when no landed meteorite is available or one is already being tracked, and the bell is not consumed when the sky is already clear.
What is the difference between the portable winch and the vehicle winch?
The built-in vehicle winch is not an inventory item. It is always available, has unlimited uses, and receives its own three-stage reach upgrade. The portable winch is a consumable tool that occupies one of your four slots.
Recommended Free Tools
| Winch | Uses a tool slot? | Reach or function | Upgrade cost |
|---|---|---|---|
| Built-in vehicle winch | No | 10 m stock; 11.5 m, 13 m, and 15 m after successive upgrades | 25 + 50 + 75 = 150 pebbles |
| Portable winch | Yes | Places a single-use anchor within the current built-in winch reach | No separate tool purchase; copies come from your owned inventory |
A longer built-in winch therefore improves where a portable anchor can be placed, but it does not create another inventory slot. Anchors remain in the world after use and can help other players, according to The Wand Report’s launch review.
How do slots refill?
Empty capacity is restored when the vehicle reaches Crazy Günther, drives into a cabin, or respawns at a cabin. Cabins also repair the vehicle. The wiki records 43 cabins; visiting one clears fog in roughly a 400 m area, so cabins are useful resupply landmarks rather than merely respawn points.

There is no automatic refill simply because you drive past an arbitrary point of interest. If a slot is empty after using a plank or jack, plan a route through a cabin or return to the mechanic before attempting another difficult section.
Which four-slot loadout should you use?
No published source identifies one universally best loadout. The right four items depend on terrain, whether you are playing alone or with up to three online co-op partners, and how close the next cabin is.
- General exploration: one repair kit, one portable winch, one jack, and one plank cover damage, missing anchors, rollovers, and gaps.
- Rocky or technical trails: replace the jack or plank with another portable winch if natural anchor points are scarce. Portable anchors can remain available to the group after deployment.
- Long searches for meteorites: carry a meteorite radar, then use the remaining slots for repair kits or portable winches. The radar tracks only meteorites already on the ground.
- Bad weather or an inconvenient night: a bell or camp tool can be more valuable than a duplicate recovery item. The camp tool advances time and gives every vehicle 25 health, while the bell changes weather but does not brighten darkness.
- Co-op support: duplicate repair kits or portable winches can help several players, but remember that the maximum personal stack is three and every item still occupies a slot.
GameRant’s launch guide recommends buying the second slot first for 25 pebbles because one slot can force a long return trip. Maxwell’s review says he usually kept at least three of four slots filled once the terrain became harsher. Those are practical recommendations, not a developer-defined optimal build.
Is the 150-pebble capacity line worth buying?
For most players, the 25-pebble second slot is the strongest early convenience purchase: it doubles what a stock truck can carry for a relatively small cost. The third and fourth slots matter more when trails become longer, cabins are distant, or you regularly need both recovery tools and utility items.
Capacity does not improve torque, grip, suspension travel, crash resistance, flood time, or built-in winch reach. If the immediate problem is climbing, deep water, repeated crashes, or an unreachable anchor, the corresponding upgrade line may solve it more directly.
| Upgrade line | What it changes | Paid stages and total |
|---|---|---|
| Tool slots | Items carried at once: 1 to 4 | 25, 50, 75; 150 total |
| Built-in winch | Reach: 10 m to 15 m | 25, 50, 75; 150 total |
| Engine | Torque, power, and speed limiter | 25 and 50; 75 total |
| Protection | Impact damage multipliers of 0.85, then 0.70 | 25 and 50; 75 total |
| Suspension | Up to 0.16 m more travel than stock at stage 3 | 25 and 50; 75 total |
| Tires | Up to 0.16 more grip than the tire base | 25 and 50; 75 total |
| Water resistance | Flooding time from 8 to 10 to 12 seconds | 25 and 50; 75 total |
A complete set of all seven upgrade lines costs 675 pebbles per vehicle: five 75-pebble lines plus the 150-pebble tool-slot and winch lines. That makes capacity a substantial but not dominant part of a fully built truck.

How many pebbles are available for upgrades?
One-time rewards total 3,285 pebbles: 2,565 from map points of interest and 720 from first photographs of 27 animal species. A second photo of the same species pays nothing. The total is enough for roughly four complete 675-pebble vehicle builds, not four complete builds plus a fifth.
After those rewards, meteorites are the repeatable source of pebbles. The published payout is 15 to 80 per meteorite, depending on size:
| Meteorite size | Reward | Winches needed |
|---|---|---|
| Very Small | 15 pebbles | 1 |
| Small | 20 pebbles | 1 |
| Medium | 30 pebbles | 1 |
| Large | 40 pebbles | 2 |
| Very Large | 50 pebbles | 2 |
| Huge | 60 pebbles | 3 |
| Very Huge | 80 pebbles | 4 |
Each area holds two or three meteorites at a time. After one is extracted, another is queued within about 10 seconds and falls one to five minutes later at a random map position. A meteorite extraction takes eight seconds of pulling while all required ropes remain tight and no two ropes are separated by more than 120 degrees. Rewards are shared among players attached to the meteorite and others within 10 m, with shares rounded up. Larger meteorites are associated with fuller sessions.
The 3,285-pebble one-time pool is only 135 pebbles more than the 3,150 needed to put four slots on all 21 vehicles. Spending that way would leave almost nothing for engines, tires, protection, suspension, water resistance, or winches. The upgrade references therefore advise concentrating on one or two vehicles instead of spreading capacity across the entire garage.
Do the prices still apply after the October patches?
The 25/50/75 ladder is tied to the 14 October 2026 release build documented by the community file references. The game received patches on 16 October, 19 October, and 30 October, including reward, quality-of-life, and graphics changes, but the sources available here do not republish the tool-slot table against a newer build. Treat 150 pebbles as the documented launch-build cost and check the in-game Mechanic if a later update changes it.
The Steam page confirms the game is a 14 October 2026 release from Funselektor Labs Inc. for Windows and SteamOS + Linux. Its store description explains the equipment-driven off-road design, but it does not publish inventory capacity or pebble prices. The numerical upgrade claims above are therefore linked to the unofficial tables that read the game data, with their build-date qualification.

What should you buy first?
- Buy Tool Slot 2 on your main vehicle. The 25-pebble price is the smallest capacity step and removes the most severe one-item restriction.
- Choose a loadout for the next objective. Do not carry a radar, bell, or camp tool by habit if the route needs recovery equipment instead.
- Upgrade the built-in winch when anchor distance is the problem. It is always available and does not compete for a slot.
- Add Tool Slot 3 and Tool Slot 4 as route length increases. The extra capacity is most valuable when a cabin is far away or a trail combines several failure modes.
- Keep upgrades concentrated. Fully improving one dependable truck costs 675 pebbles; spreading the same money over many stock vehicles produces less capable specialists.
The practical limit is not the number of tool types but the number you can carry before the next resupply point. Four slots are enough for a deliberate loadout, never enough for every tool at once, and only apply to the vehicle on which you bought them.
Frequently Asked Questions
Can I change my tools without paying for the slot upgrade again?
Yes. After a capacity stage is purchased, removing and re-equipping that stage is free. The pebbles are charged for unlocking the vehicle’s capacity, not for each later loadout change.
Free tools Windows power users keep installed
One-click scans. No signup required.
Does a cabin refill tools for every player in co-op?
A cabin refills the slots on the vehicle that reaches it and repairs that vehicle. Teammates need to bring their own vehicles to a cabin or use another refill point; the camp tool’s 25-health effect is the separate action that affects every vehicle in the session.
Can I carry duplicate portable winches?
Yes, up to the number of portable winches you own, which the tools reference lists as three. Each copy occupies a slot, and every portable anchor must still be placed inside the current reach of the built-in winch.
Do tool slots increase the number of tools I own?
No. Ownership caps remain unchanged after all three capacity purchases. The upgrades only let the selected vehicle carry more of the items already in your inventory.
Is the four-slot limit different in online co-op?
The per-vehicle limit remains four in co-op. Cooperation expands what the group can bring because up to four players can carry separate loadouts, but it does not give one vehicle a fifth slot.
