I'll chime in here. I'm in south Louisiana where the summer temps are upper 90's with 90% humidity. It is sometimes oppressive even to people that grew up here. I don't find the black paint to be much different than any other color. The air conditioner works just fine.I apologise for going off topic here but what's it like to live with a black cargo van? Really hot in the summer? Maybe a little warmer in the winter?
