I'm always torn with the way one minute the 20" wheels fill the arches and make a van look sleek with a 35 profile tyre then I see an unlowered van on 20s with higher profile tyres and if it's an SWB it looks short and chunky almost swamper style, on the other hand I run 18s and at times they make the van look chunky despite lowering, another day though and I'm back in love with their looks and nimble handling!
