I install the edge juice attitude recently. I played with the setting for a little at first. For about the last 1,000 miles I have left the setting at 3/5, and the allison is still shifting pretty hard. I've heard it has to re-learn the conditions.

When I get ready to tow my 11,500# camper and put the juice setting back down to 1 or 2, will it have to start over re-learning and will it hurt any thing?

I never got my juice box at #5 to shift smoothly but I never left it up thsi high for an extended time. From 1-3 it's very smooth. Every time you change the load, it seems the tranny has to relearn it's shift points. Ideally you should not keep changing the #'s on the juice box. Set and leave it unless you need to tone down to tow. I've found my tranny shifts hard after I tow but calms down some after 20 minutes of stop and go driving.
