Are earlier Coleman and later Fleetwood bunk end roofs Sunbrella material like the sides? I am going to go to local canvas shops to get a quote on 'just replacing the bunk roofs' on my '99 Starcraft Pup. The canvas shops obviously use a LOT of Sunbrella, so I'm wondering if that would be a good choice instead of new vinyl roofs? Would a gray Sunbrella color absorb any less heat than a gray vinyl. I know that the more color/tint the more heat the material absorbs. I'm wondering if I should consider for the roof ends, a white or 'very slightly' tinted color to reflect more heat? I'll still have the Aqualon (vinyl) sides. I am adding a Fan-Tastic vent fan which should really move some air when we are inside on hot days.
