I've got a full set of rainbow screens thermal blackout blinds custom made for the granvia - sold my van so they are up for grabs.
http://www.ebay.co.uk/itm/-/172770952724?
exterior blinds for front and side windows, rear and pop top
interior blinds for sliding door window, near side rear rear, offside rear front, offside rear rear square (for side camper with wardrobe bit) and standard offside rear rear (which i haven't tested, but is mirror of offside rear rear) plus insert for the little window in the pop top
these are great, and extend your campervaning year, and your ability to have a lie in without small people going mental at the first sign of daylight
they cost 650 with 10% discount for taking my van to be measured - 300 to anyone on here, offers welcome
granvia@unclerob.net or 07702256784 for any questions/more pics or arrange to have a look/try (free cuppa whether you buy them or not
)
cheers
