>aren't you already supposed to unload your vehicle before you jack it up on one side? Eh, maybe? You have to take the totality of circumstances into account. The jack (depending on the style, some are better than others) can probably take the weight in most circumstances. The vehicle can probably also tolerate the extra weight so long as it's not grossly overloaded or rusted. Whether you have any problems is going to depend more on the details of the location more than anything else. You could go on Reddit and score a bunch of virtue points for saying nobody should ever jack up a vehicle in less than perfect circumstances but I think in the overwhelming majority of real world situations you do not need to unload the vehicle.
