The King setup in the Carli Pintop 2.5 leveling system was what I was going with originally but thanks to having the differences explained between the King and Fox 2.0 Resi, I decided to go with the Carli Back Country 2.5 leveling kit which comes with the Fox Resi 2.0. I felt like I didn't need that Pintop kit because I do not plan to go Baja with my truck, lol. In addition, the price tag difference between the two kits is quite a hefty amount but the performance and quality is unsurpassed either way you choose to go. As far as my sales experience, Chris (SmokinStroker) really hooked it up and he is an awesome dude to deal with!
Best of luck to you and let us know how it turns out.
