I'm not sure any color van would have made a difference that day in Eastern Wa haha... That being said I bet a white/lighter van would do a little better with the heat.. Hard to say. A bigger difference maker would be better/thicker insulation! ...or AC!Read through the build and it looks awesome! Nice work . I'm curious how the inside temp is with that paint color. I'm thinking of going with that color but am concerned about the potential internal heat impact. You mention that it was very very hot in Eastern Washington, did you feel that inside the van?
