Looks great so far!
I have several pictures of Brad Wike's Duel truck on my Flickr page. It is supposed to be one of the surviving trucks from the movie. There was also an episode of "The Incredible Hulk' called "Never Give a Trucker an Even Break" that used one of the surviving trucks as well as a ton of scenes from the movie. There a a few inside shots of the swamp cooler in the Hulk episode. I believe that you can find it on Youtube. Brad Wike's truck and the truck in the Hulk episode do not look the same on the inside. Brad's truck was originally a 281 and I think that it had a Page and Page suspension, but it has since been converted to dual drive with a newer suspension similar to the one found in the AMT Freightliner kit.
