Please, please, at the very minimum, read the -10 TM.... These are not large pickups, they're essentially commercial trucks with lots of unique quirks. There are things you need to understand and tackle before you drive it.
You need to understand the braking system, emergency shutoff procedure, and parking brake at an absolute bare minimum, but I highly suggest you read the - 10 TM in its entirety. A couple weeks of bathroom trips will give you enough time to read it, a couple pages (one section) at a time....
If you're not familiar with air brakes and how they work, what safeguards they have and how they function, etc. you're gonna need to understand them before you drive.
I can't stress enough the importance of this, as it's not just your life you're dealing with, it's everyone else's on the road.
That being said, congrats on your purchase, welcome, and have fun!
