We're ordering brand new custom vinyl seat upholstery for our mid-blue and white Dormobile. The seats will be mid-blue (to match the lower van exterior) and off-white (to imitate the upper van exterior).
Mike at Campershak made a beautiful job of our upholstery http://www.thecampershak.co.uk/galleryimages.php?galleryid=404 Sent from my A0001 using Tapatalk
When I did my restoration I had and 'off 'white vynal outer with a with the center material coloured to matched with the ouside colour (wife calls it a mint clour) of the bus.
piping is always going to get mucky because of where its positioned ... i'd go with coloured piping. think about which parts will get dirtier faster (seat pads, lower panel cards) and go for the darker colour there
