I carry a front storage box that loaded probably runs around 250-300lbs and don't notice it at all on my F250. I mounted it low enough not to block the grill. I would recommend putting markers of some kind that sticks up in the front corners so you can see where the front of your van really is. I used the orange fiberglass driveway markers cut off to stick up a little above the hood and made mounts on the front corners. I then wrapped some extra reflective tape on the top couple of inches. Even with the markers right in my face I have come close to running into light poles in parking lots when parking because I forgot it was up there.
