This is a good contrast to what I was talking about in designing a rig for primary Moab use. Despite your significant lift advantage you drag your rear bumper a lot worse than I do, because the location of max up travel on the two lifts is about the same, which in this type of flex compresses the suspension about the same. The difference is my rear overhang is much shorter.
In a rock garden things would be different, because my rear bumper clearance would make no difference to getting hung up on control arm mounts, resting on sliders, etc.
Designing an 80 for Moab definitely includes the sawzall
