Transporting a cham by car

[heebie_geebies]

So I am researching a purchase of a male Veiled cham at the upcoming Red Deer show. I live in Saskatoon, which is an approximate 6-hour drive away. The show is Saturday and Sunday. I planned on picking him up Sunday then leaving straight for home. That should provide the least transport time and jostling around therefore less stress. My car has a/c so it won't get too hot driving under an August sun (obviously weather pending). I was planning on borrowing an infrared temperature laser to make sure he's got the right temps. But other than that, I don't know what his needs for transportation are. (Too bad chams can't talk.)

What is required for transport cage?
Covered cage or uncovered cage?
If possible, in the sun or shade?

I haven't been able to locate a thread or a site with such information. So anything you folks can suggest or direct me to would be much appreciated. I want to provide a first class trip to his new home. However, I think I will skip the en route movie and champagne.

Thanks a bunch!!
