I've seen that video before, but it was sure worth watching again. That truck is one of the rare ones where it is only a 4000 Model, but yet it has the Wide Front Fenders on it. The 4000 Models and even most 5000 Models from '63 to '66 usually have the narrow fenders. Looks like it was ordered with a heavy front axel. I do believe I noticed 10 Lugs on the front.
