Wasn't the AMT Peterbilt 352 reisued in 2000, or something like that? That's about when I got back into truck mudeling, and i seem to remember a bunch of then floating around.
I think it boils down to two things: personal preference & ability. I don't weather my models primarily because I don't really know how to. I'm learning things, and I might try some weathering in the future.
Fleet looks really nice. The General came out really well. There's just something about the GMC General for me. Nostalgia, I guess. All those GMCs and a lone Ford.
Something about allowing the trailer to turn properly. At least that's what people who know a heck of a lot more about logging trailers that I do told me. Maybe it's just a Pacific Northwest thing. The log trucks around here don't use trailers.
For being 19, you have some very impressive models. Wish mine when I was your age looked half as good as your's do. They're very nice.
Quick photography tip: don't have your light source behind your subject. Your photos will always turn out too dark. It screws up the light meter.
If I remember correctly the Ford Model AA (truck) shared a lot of parts in common with the Ford Model A (car). Same for the Model B & BB. When Ford introduced the F-Series in 1948, that had no parts in common with the Ford cars of the era (ok, maybe the engine).
Looks pretty good. Ok, so it's not a contest winner. Neither was my first one (or second, or third, or fourth for that matter). You're next one will be better.
If it's a Cummins, it's probably the NTTC400 like Revell's Peterbilt 359 kits.

Good luck. Have fun. Post pics when you can.
No one that I know of makes a Sterling conversion, so your sort of on your own. I suppose that you can start with the AMT Ford LN8000 or LNT8000 and modify the hood, change the engine, etc.
