What did you do to make the paint job so realistic?

This is better than I could ever do! Congratulations are in order.

I noticed on minor detail missing - Bumper markings. I saw that one side was complete but there are markings on both sides of the bumper (as you are looking at the vehicle from the front the left side of the bumper holds the unit identification and the right side is stenciled with the actual bumper number (ie: HQ-12)).

Howdy Vodnik,
Or, is that your real name!?!

Just make's me think if just maybe you're a 'ringer'. You know, maybe a Content Editor for MMIR, or a Technical Writer for FSM, or even a Graphic Layout Artist for Adobe! Maybe you're just using a fake 'stage name' so none of us find out your cunning little secret!......yeaaaahhh, maybe that's it Mister! You're really a spy for Tamiya!....oops, ...no, I meant Osprey Publishing!....no, wait a minute.......Microsoft!.....Yep, he's a 'spook' for Bill!

Now, your assignment is to cook up one of those wonderful article's at least once a week!
Maybe twice a week . Just stop eating and sleeping. Rumour has it, those sustaining habits are overrated anyway...

Can anyone tell me if the US Marines use this truck???

That is a great paint job you done there, but what I was wondering, which it makes it hard to see on the computer, but what you are calling brake chambers, isn't that part of the automaitc tire inflation devices, to the best I could see there isn't any brake chambers, or s cams that go to the wheel to apply pressure to the brakeshoes, every truck I ever seen has the brake chambers connected to the axle about a foot back from the wheel, which that would be pretty hard to make, but it could be simplified by putting backing plates on the back of the wheel, that way you wouldn't haft to make brake shoes or the other parts, now a brake chamber looks close to to what you pointed to, but with a rod going out to the slack adjuster, and in the slack adjuster a round shaft goes toward the wheel to an S cam inside the wheel, which when it turns it spreads the brake shoes out against the drum, of course unless it has disk brakes then it is another whole different ball game.
