The hardest things is going around the van. You need a big circle preferable on a larg empty space so the background can be out of focus.
Place your camera on at least 36 places on this circle pointing example to the center of the circle.
Some large ad firms have a platform for this that can rotate
36 positions are far too few. I shot a small sports-scar this way using 250 positions - you need a lot more for a van, because the circle has to be rather big for achieving smooth moving.
36 position will make it look like a flip-book resp. time-lapse.
But the real problem is: you need an absolutely constant distance - seen from the center of the car. With a van that´s almost impossible.
So the only real useful way is to place the van on a turntable and aiming the camera straight to it´s center.
I´ll look to find my car-object pano and will show it here.
