Editing my comment.
I was having some mod conflicts, but it wasn't this one! (It was Maize Plus, or the Baling Twine Addon) So it seems to be working much better now.
Pretty excited to try this out! A few things I'd suggest:
The window tint is pretty dark.
The air compressor keeps running, I assume it won't on the real truck. Maybe it can be the start-up sound, and after the brakes are applied?
The air compressor sound is now applied to other electric tractors.
It shows a fuel guage instead of a battery indicator. Would this truck have both, maybe? I'm not sure how the diesel generator would work in-game.
Somehow I can't open the tarp on a grain trailer, it will only open the hood.
I can't wait for the update, but very much a thank you for getting the mod out so quickly!
