I'm running Cooper Discovery AT3 on my truck in roughly that size 315/75/16 and in the 10k ish I've put on them have been very happy with the tread wear and road noise or lac there of, not to mention they were about $30/tire cheaper than the standard BFG AT.
My brother has put them on his '99 SD in a 285/75/16 flavor and he has said that he was rather surprised with their ability off road in the mud of GA red clay.
