There is a difference between the discussion on what happens during a dynamic situation such as suspension travel and what happens in a static situation such as being discussed - - - alignment specs after bars are cranked. I wasn't talking about suspension travel though, I was talking about using the keys to jack one all the way up. I know from getting paid to use a Hunter DSP600 infrared LED aligner that once the bars are cranked up, you have to make fairly large adjustments to the CAMBER. In this case you're left between having enough caster to drive correctly or havng the camber be far enough off to wear tires. There is not usually enough caster for proper steering return and highway stablility when the bars are cranked and the camber is in. 2.5 degrees or so is by far the most you'll get out of a GMT800 half ton 4X4 with the bars cranked. I like them at about 3.3 LH and 4.0 RH.
