When we bought our B last year it came with 3 ways of blocking the front windows and we have tried all 3 and have settled on a fold up foil/foam front window block and my wife made curtains with super magnets sewn in the seams for the front sides. We also have a 3 sided curtain that goes up with velcro, this a bit of a pain to put up. Both of these do not block the front seats. The third is a curtain with rod that normally hangs in the back, pulled back, but can be move to the front and hooks into side hangers. It is nice for short stops like in rest areas and Walmart where you don't want to be obvious you are sleeping in the van.
I like the fold up ones that pasusan suggested, I may replace the foil with one, takes up less space when put away.
