I have a 2014 Limited 4x4 hd towing pkg. I tow a 22" V-Nose all Aluminum car hauler. Trailer is 2,700lbs vehicle is 3,200lbs with gear etc I'm around 6,500#. I get 8 to 9 mph normally without headwind or mountains. Not tried premium while towing but that is something I will look into. I just hit 111K miles and likely could use a set of plugs, that may make a difference as well.
