Build for the night, not the screenshot.

How to use the builder

1. Choose the rig. A car + trailer is the best-documented mobile base. An RV is the larger option. A fixed base or garage uses the same functional categories but does not need mobility.
2. Choose a priority. Warmth first is the safest. Range first prioritizes fuel and recovery. Living comfort is a luxury choice, not a survival plan.
3. Select only the modules you can actually build. A blueprint or a confirmed module name is not a promise that you have the materials.
4. Read the build check. The tool flags missing heat, power, storage and recovery categories. It does not invent a wattage budget.
5. Write notes. Record the crafting order, the power source and where the critical boxes live.
6. Save or print. The plan is stored locally in your browser.

A sane build order

1. Heat. A heater or a reliable fire setup. A cold base is a failure state.
2. Power. A battery and a generation method. Benches and lights need electricity.
3. Storage. Cargo boxes or transport boxes. Loose loot is a storm liability.
4. Food and water. A cooking bench and a pantry reduce the number of supply stops.
5. Workshop. Crafting bench and spare parts. This is what turns the base into a repair station.
6. Utility. Resource and storm scanners. Strong, but not foundations.
7. Comfort. Bunks, radio, microwave, instruments. The reason the base feels like a home.

The trade-offs the game does confirm

• Trailers consume fuel when attached. A base that moves costs fuel even before the generator starts.
• Trailer crafting consumes fuel. A workshop session is a fuel decision.
• Generators consume fuel. Power is not free just because it is on board.
• Blizzards move objects. Secure the base or the storm will rearrange it.
• Weight changes driving. A loaded trailer brakes and turns differently from an empty one.

What the tool cannot know

• Module power draw, battery capacity, solar output and heater fuel consumption.
• How many modules a trailer or RV can hold.
• Whether every module fits every rig.
• Whether bunks trigger a sleep mechanic or only a comfort state.
• The exact fuel penalty of a loaded trailer.
• Whether the storm scanner predicts tornadoes or only blizzards.
