I think it depends on the brand you choose.
When I was shopping for my unit I really didn't pay attention to that. Its not an option that I would order. If it had them I would take them rather than place a new order.
I need to carry wood blocks to go under each jack foot, might as well just use them to level it under the tires as needed. That's what did in the past and find it easy enough.
I hardly ever use the jacks. My mechanic uses them when he is working on my rig in his parking lot . He finds it easier to do that than bring it inside and use a lift.
im up early, heading out fishing...wish me luck .
