Levelling:slide out or in?

[Realer]

First off thanks for the great info on this site. So I just want to ask what people are doing for setup. I have always leveled the TT side to side, unhook, level front to back, stabilize and then put slides out. I have just replaced the scissors jacks on the slide-out side of the TT and was wondering if the added weight added to them after putting the slides out caused this? Does anyone put slides out and then level side to side?
