Yes and it holds gears great on hills!! The 6.2 has an amazing amount of power pulling that much weight. Cruise set on 70 and 3200 rpm was as high as it got climbing hills. Spent most of the time in the 2200 - 2700 rpm range

Driving in stop and go traffic mine doesn't shift the way I would expect.
Just got back from towing my 9000 pound trailer and it shifts awesome when loaded
