Want to install take off TRX wheels and add Airlink suspension links on 2020 limited with four corner air suspension. Anyone have this set up?

[Dw1973]

I have a 2020 Limited with factory four corner air lift. I want to replace my 20 inch stock wheels with take off 18 inch TRX wheels with LT 325/65R18 tires. I am interested in buying the Airlinks suspension links.
I have some questions as the airlink suspension website is vague. Thanks in advance.

1. Do I need just the front Airlinks or the rears too?
2. Do I set it to off road 1 and just leave it there after installing the Airlinks? How does this work?
3. Any rubbing at all?
4. What happens when the truck goes to aero or normal ride? Rubbing?
5. What's the ride like?
