Just to rule out the stabilizer, I would take it off and test drive the Jeep. Just to see. Stabilizers can be very deceiving in hiding issues and it's the one part you can't get inside of to really see if something is wrong with it.
Agreed ^^^^
I would say 10-15 degrees.
That sounds 100% normal in my opinion/experience. It's pretty normal to see that much when you're checking it at a stop (like in your driveway).
Agreed again ^^^^
