So Jo, I am in the same situation. I put a locker up front with manual hubs. I have done nothing reference the TOD. Based on what I have read here if you disconnect the TOD wont you only have 4LOW.

Do you think you will never have a reason to drive in 4HIGH or is it not a good idea to use the TOD in 4HIGH with a locker? ( I am talking about off road, I know you cant use it on the street.) I have done one off road trip with mine since I have added the locker and I used both 4H and 4L.

Anyway, can't wait to see you again in Moab.
Side note, but related topic since both of our upgrades came out of necessity after last years trip!
