First and foremost, the new camera is awesome! I've been playing since the tech demo, and to finally have a camera option like this makes me so glad I bought Mudrunner.
Now that I've got that out of the way. For those playing with a wheel and H shifter, there's no low range option. I get it that this is not an issue for those playing with mouse and keyboard or controller. Or that it has any negative affect on gameplay, but it does feel odd driving around in high range all the time. On top of that, if low range were to be introduced for players using clutch + H shifter, it wouldn't make much sense if using the throttle was still necessary get the truck moving while in low range.
I don't know how difficult something like this would be to implement, and since it would only pertain to a smaller group of players, if it would even be worth it. I just think it would be nice to have something like this, and really up the realistic factor.
