Tanker Truck

[PTTG]

It would be interesting to have an option like the train's tank car that drives around freely like the car.

This would be quite awesome. Never crossed my mind even. But I think it might be finicky to park in just the right spot in order for the pump to extend it's arm...

You might even be able to get that right if you're driving manually. But having to park exactly in the right spot would make such a car useless for the really interesting stuff (i.e. programmed vehicles that automatically look for a path between predefined waypoints), I'm afraid.

You can use the truck with barrels, another way is pretty impossible or CPU expensive.

What about using a system like this?

At that point you could just use trains unless you like the aesthetic.

Totally possible with AAI in current state if you make barrels. But I couldn't make it running properly as it requires heavy circuitry with combinators to overcome very derpy AI of trucks.
