It would be great if the Miner: Container Ramp could store one container that can be used to increase the capacity of the Miner. Just build the Container Ramp, drive a container to it and select Load Container. This would take the container from the Rover and store it on the Ramp and it used as a storage extension. Then you just drive up again with thhe rover and select unload container and it moves the container from the ramp onto the Rover again. This way you can drop off a container, wait a while, then come back and get it. You could even make it that the Miner does not have any storage and relies on the container for storage.
