I didn’t see one, so I figured I’d make one
Alternator: Charge storage batteries via a gas engine. Doesn’t consume extra fuel, you just have to drive. (don’t know if this is behavior that already exists to simplify headlights)
I noticed I don’t think the RV Unit takes energy to run. Seems a little overpowered, though I have noticed a tendency for me to run a ways away before realizing I can’t cook if I don’t carry the right materials.
Tank, battery, solar panel info: I couldn’t find in the text or wiki on actual numbers for this kind of thing, like % charge per time, capacity, etc. Couldn’t even find info on whether or not water tanks could be filled with clean or any water.
Do headlights even take power? I see them on gas cars I think, but don’t see storage batteries.
I just had an idea: a flat-bed or trailer add-on (attached by applying a chain), so you could make a motorbike/buggy and park it in a heavier vehicle. Would be convenient to drive through a town on a small vehicle, but leave your home fortress on the outskirts.
