If those EGTs are from towing on flat terrain then I'd say they are a little on the high side for 8500 lbs. Some of that could be the low RPMs, but hard to say as I have 4.10, so hopefully someone with the same set up will give some feedback. For me, at 70 mph towing roughly a 10,000 pound 5th wheel I will see EGTs between 700 and 850 with the RPMs around 2300 rpm on flat terrain.
In the mean time I would be checking for up pipe leaks or boost leaks
