First off congratulations.
Only word of advice is to do a 2nd walk around when you think you are ready to go checking lights and visually check the jaw is shut on the hitch. A "tug test" is also a good practice. Just hold the brake controller slide to set the trailer brakes and give the trailer a little tug with the truck to make sure everything is properly connected.
Empty parking lot makes a great place to practice backing.
Be safe and have fun.
