My 1961 VW panel van weighed 1750lb and had a 3/4 ton rated axle.
If they are needed, it is usually on the front, but this shape has plenty of length to avoid abrupt transitions with. The dimples raise the skin friction considerably, while only letting the wake follow that stylish curve to the transom a few degrees farther. A conventional smooth top and sharp cutoff would be much slicker. This guy is just trying to sell his art with a false rationale.
There is no excuse for a land vehicle to weigh more than its average payload.
