Looks like an interesting project. Interesting that you say "yellow & green", because in the video it looks like yellow & blue. The pic on Hank's does look yellow & green, though.
Maybe we should point Fred in his direction. Then we can get the kits one by one. I'd deffinately take the AMT Kenworth, a Transtar II, and maybe a bulldozer,
A good match for Alpine Green is Testors Model Masters Grun RLM62. The Detriot Diesel Alpine Green from Dupl-Color is (in my opinion) too dark & too thick.
Didn't you start on the LoneStar P/E set? Do you think there will be one for the ProStar?
As far as steering wheels go, some "stock" modern & 1990s steering wheels would be nice. The AMT steering wheels just look out of place in modern trucks.
