Sounds pretty normal to me? Given that it's a large vehicle with a low powered engine, going up a grade in higher altitude is gonna be hard and it's gonna have to work.. (ie higher rpms)
Try pushing a wheelbarrow up an incline with a load in it compared to on the flat land..
Anyway, not sure why semis passing you is "white knuckle", but I was not there and probably missing some points along the way too..
4000 rpms is loud for sure, but that's probably the peak power range of your engine, so it's just doing what it needs to do..
Good luck! Mitch

I was going to write pretty much the same thing. Nothing about the story is "white knuckle", so unless there is more to the story...
