Rotissries make working on floors or roofs a hell of a lot easier than with a car on stands or hoist. I have done the prep work on a number of rally car shells on a rotisserie over the last 5 years and I would not do it an other way. Just make sure that the mounting point for the body sits 300 to 400mm vertically below the pivot point for stability as a van would be fairly top heavy. I think if the pivot point was in the same plane as the mounting point that the whole rig may topple over when you try to rotate the shell.
The only draw backs are tey have a bigger "foot print" than a shell on stands and most rotisseries I've seen require a second pair of hands to rotate the shell but that is well outweighed by how much more pleasant it makes a car to work on.
I have some drawings for the unit I built but I'd be unsure how suitable it would be for a van as was orginally made for a Hyundai Excel.
