ROB RUN Vehicles Guide: Cargo Slots, Trunk Rows and Upgrade Fit
Updated · RobrunCodex
Choose the vehicle for the load: ordinary inventory uses trunk rows, while cargo needs dedicated slots. Trunk Bags and Cargo Racks are different upgrades. Rentals cannot be upgraded; owned modules must fit the model and slot. Changing vehicles drops the previous trunk contents rather than moving them automatically.
Measure the load before choosing the car
A faster vehicle is not an improvement for a delivery it cannot carry. Decide whether you are moving inventory, cargo or just the character before buying parts.
- No eligible owned vehicle
Use a Parking Terminal rental when you have no active vehicle. Keep upgrade purchases for an eligible owned model.
- Inventory haul
Compare trunk rows and compatible Trunk Bags. Item footprints still determine what fits.
- Collection or production cargo
Count dedicated cargo slots. A Longhorn with three Reinforced Cargo Racks reaches 12; Buletti Soltempra has none.
- Module or vehicle change
Check the part’s model and installation location. Plan unloading before a car switch, then inspect the installed result on the key card.
Choose ownership and the vehicle for your load
Owning a car requires a house. Without one, use rental vehicles from Parking Terminals; better rentals require higher district levels. Rentals cannot be upgraded, so do not buy a part expecting it to fit a temporary car.
Owned vehicles and installed improvements survive player death. That is a death rule, not confirmation of federal-reset persistence. Buy vehicle keys through the base laptop after the matching research and district progression.
Separate trunk inventory from cargo slots
Ordinary items use inventory rows, while cargo uses dedicated slots. Trunk Bags add rows and Cargo Racks add cargo capacity. Neither upgrade substitutes for the other, and compatible quantities depend on the exact vehicle.
Longhorn Van with three Reinforced Cargo Racks reaches 12 cargo slots. Buletti Soltempra has no cargo capacity. If your task is a collection or production delivery, the fast car can be unusable for the load even while it remains good transport.

Worked load check: eight cargo objects and an attractive sports car
An eight-object cargo delivery cannot use a Buletti Soltempra’s zero cargo capacity, regardless of speed. The documented Longhorn setup with three Reinforced Cargo Racks reaches 12 slots, leaving four slots after eight cargo objects. This is a capacity check, not a claim about the cheapest vehicle or safest route.
If you already have inventory in another trunk, changing cars drops those contents. Plan the loading sequence deliberately. Drawing a weapon while carrying cargo also drops it, so the trip from the storage position to the vehicle is part of the delivery plan.
Research and install a matching part
Parts are researched, then bought on the base laptop. The research follows the matching vehicle progression and higher part levels unlock sequentially. A final part price does not include every earlier node or its actual purchase.
Use the matching installation point: modules can fit under the hood, in the trunk or on the underbody, depending on the part. Move the carried component into its corresponding slot and inspect the key card afterward. Speed, acceleration and handling values shown there let you confirm the installed result. Do not treat a part as a universal improvement to all three statistics.

| Improved ECU | Improved ECU | Top speed | $160,000 | $75,000 | II |

Reach the underside before fitting an underbody part
A compatible part still needs the correct installation point. Hood and trunk interactions are not a substitute for access to the underside. The service-garage example below uses a lift at the Gas Station to reach that area.
Bring the researched and purchased component, inspect the matching modification slots, fit the compatible part and check the installed result on your vehicle key card. Accessing a lift alone does not install a component or prove a performance gain.
Reach the car's underbody with a service lift
The example uses the Gas Station service garage and lift. Check the part's compatible slot; this clip is access to the underside, not a comparison of installed performance gains.
Watch the interaction · 0:25–1:05
Plan a loaded transfer before changing cars
Switching vehicles drops the previous trunk contents. A car change does not automatically migrate the haul. Unload deliberately and prepare the next vehicle’s item rows and cargo capacity before switching.
Drawing a weapon also drops carried cargo. During a chase, a full vehicle is only useful if you can reach a buyer or exit; Police can ram cars and temporarily obstruct bridges. Choose handling and route with the task, not top speed alone.
Vehicle Police Radio and replacement planning
The installed Police Radio reveals nearby patrol vehicles and the city event feed. It remains on the car after driver death. Access still depends on the equipment’s own requirements, so owning a suitable car does not automatically grant the radio.
For the next upgrade, compare a specific bottleneck: more bag rows, more cargo slots or one driving statistic. This keeps research and purchase spending tied to a job you can complete instead of fitting unrelated parts because they are available.
Common questions
Why does more trunk space not let me carry cargo?
You may have added inventory rows with Trunk Bags. Cargo needs dedicated slots, usually improved through compatible Cargo Racks.
Why will my part not fit a rental?
Rentals cannot be upgraded. Use an eligible owned vehicle and check that exact model’s compatibility.
Where do I check whether a performance upgrade worked?
Inspect the vehicle key card after fitting the part through the hood interaction. It shows updated driving values.
Why did my old trunk contents drop when changing cars?
Switching vehicles drops the previous trunk contents; it does not transfer them automatically.
Does surviving death mean my upgrades survive a federal wipe?
No such persistence follows from the death rule. Federal confiscation is a separate event.
Do all vehicle modules go under the hood?
No. Installation can be under the hood, in the trunk or underbody depending on the modification. Follow the matching model and slot, then inspect the key card for the result.
