I like having the surround camera I find it very helpful in tight places to see the clearances, which I get into often enough. I use the mirrors when backing the truck, old truck driver here. Next favorite is the blind spot monitoring. The cruise control is different, you have to learn how the truck is going to respond. We've had it in the car so it wasn't such a jump for me. The automatic braking, eh, its got some more refinement needed. Biggest thing here is to go slow even when you are in your own driveway, even though you've done it a million + times.
They are all just "tools" to enhance everyone's safety, but they are in no way meant to allow you not to pay strict attention and not accept the responsibility of operating a motor vehicle.
