Hi everyone. I'm still learning about the Vanagon and all its = iterations, and I just learned that later vans have a rear A/C system = that reduces the width of the rear opening. I managed to find a picture = of this (nice shot of it on www.vanagon.com in the 1990 dealer brochure), and it sure does reduce the opening. Can = someone out there with a van like this measure the inside width of the rear opening? I measured an earlier van without this when I first got = the idea of getting a Vanagon, and that was plenty wide. However, this A/C = duct could change things. Can anyone help? Thanks a ton!
