Having collision on rocks that sometimes sends your truck into space or into the planet is not challenging its annoying. Another bug I found is that the host can drive around the map and not have problems but if someone logs into his games they run into more glitches while driving. I think that this has to do with the host starting a base and mining stuff leaving big holes that are not loaded for the person joining. As for a server my whole point was to only have 4 people in one game at a time not anymore than that, so I highly doubt you will run out of stuff to farm.
