I tried to go thru it but its an hour long and its drug out and they never state the 10 reasons. They get an F for presentation.
When I had my shop and I installed a lift kit, I kept the Jeep for another 2-3 days and I had a place I could go locally that I could turn the suspension. FEW shop do that and the reason why is because you don't get paid for tuning.
I learned under one of the top builders in the US and because he gets Jeeps shipped to his shop from all over the US. He allowed me to spend 2 weeks working with him at his shop. I learned more in those 2 weeks than you could imagine. He taught me more tricks about how to make the suspension work, it was incredible working with him.
This is why you order a suspension or have a shop put one on, it does not always work as you think it should. Bolting it in is easy, tuning it is a whole 'nother game and is where pro's who are builders turn you Jeep into safe & trails spanker.
