thanks for the welcome everyone!
Yes, the van is tall enough for me to stand up in, the ceiling is about 6' and i'm only 5'3" so it's plenty roomy for me.
it actually has 7 windows in the box, if you count the 4 in the back barn doors and the 1 in the sliding door, but only two windows open. Great for morning light and enjoying views.
I took the van down to california and the blue paint did make it quite unbearably hot during the day. I am thinking of painting at least the roof white, or maybe a pale yellow/golden. The roof needs some work anyways, I've had a few leaky spots and the seams need to be resealed.
I just got some reflectix to put in the windows, so maybe that will help in the hot months. I'm also thinking of experimenting with a little fan powered swamp cooler out of a 5 gallon bucket.
My friend has a little grey toyota van that stayed super cool in the desert, so the light color does make a big difference.
I've done just enough on the conversion to make her cozy, but none of the systems are in place yet (water, battery power, solar etc) so I'll be diving into new territory when I tackle those.
