Looks really nice, Neil. Your MaxxForce is quite nice.
Shawn is correct, your seat bases are reversed. I know, you built it to the instruction booklet, but the instruction booklet is incorrect.
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.
