I live in Virginia and am picking up my new diesel in New Hampshire. I'll be there for about 3 weeks giving me time to put on the 500 required miles of break-in before hitting the highway. If I put on 500 to 600 miles while there, question is...would you recommend oil change, rear diff change and allison spin on before returning home??? Its 620 miles home to Virginia. Or am I better off doing it when I return...where there will be somewhere between 1100 and 1200 miles on vehicle??? Thanks in advance!!!

Maybe just the rear diff after your 500 mi break in. The trans spin on after 5k.
