This is how I do it now that I have one Andersen leveler. Need to get one more though.

Andersen levelers are AWESOME!!!! With my large pin box level I recently, just pull in, look at the level to see the low side, put Andersen levelers on that side, then pull forward slowly watching the pin box level until side-to-side is level, unhook, then up or down on the landing gear for front to back level using the small little level I stuck on the side.
I used carpenter levels the first time and got the trailer perfectly level before putting the stick on bubble levels and pin box level.
