I used the stock in game electric tractor sounds, not sure why the air compressor sound would be stuck on, but i will look into it. didn't have a ton of time to test everything, the grain trailer tarp button should move to another button when the truck uses open cover, I wanna say Z maybe.
also havent found a good way to do fuel and charge yet, but am working on it.
glad your liking it so far. will fix the tint in an update:)
