I did this is my driveway, may have been one of the first to do it, spoke with customer support a lot, they even corrected the instructions a bit based on my installation process.
I’m no professional by any means but good planning will ensure a fairly straight forward install here. Also, I can’t praise RC enough when it comes to their customer service, they really took care of me.
Cutting really is just for tool clearance, it’s not much, it’s not near anything scary or anything. If you have an angle grinder you’ll be fine. I would probably recommend getting their torsion bar tool though.
Let me know if there’s anything specific you’re not sure about still.
