I wonder if it could be exhaust system components, maybe a tailpipe with a broken hanger?  Sounds like something loose touching frame or body??

datalog the transmission, could be the TC shutter or another trans issue, what tranny you got?

 

try driving in M4 or M5 see if it goes away, if not hit towhaul  and leave in M5 mode. this might disable the tcc , M4 or M5 will shut off v4 mode manually

Do you have an aftermarket or muffler delete on the truck? I know I had one that when the fuel management system kicked in it would sound like a helicopter rotor.
