What a great place to run, we just don’t have that sort of terrain in the south east, unless you’re by the coast but then you risk rusty workings!
It’s a cool truck too, I like the flat green and black look. Have you looked into strong velcro or magnets to hold the cab on? Then you can get rid of the snap pin mounts through the bonnet to aid scale appearance.
i did consider using velcro or magnets but when the body arrived I noticed that the holes had already been pre-cut so decided not to try and get rid of them had they not been there i would not have made them.
