First Time Taking My Cat

Hey! I've been a truck driver for almost 2 years and finally started working for a new company that will allow pets! I have a female cat (7 years old; fixed) that I will be taking with me and that I registered. Any advice is welcomed! This will be her first time in the truck and even my fiancé is coming with me (passenger policy) so he can help her out as well. She's easy-going when in the car, but I know it's a huge difference between being in the car and in a semi. I want this to be a great experience for her.
