yeah my exhaust got deeper and louder . My truck only really uses Def towing heavy especially in mountains or windy . My Trailer is a bumper pull its kinda heavy 7500 lbs . My buddies is a fifth wheel and 8500 lbs and gets Slightly better mileage and towes way better. I've got wdh and sway bar just the difference between Trailers I guess. The trucks are great 9.5 to 15 towing
Thanks superiorrockwall,

I understand you use most of your DEF when you tow but, when you say your DEF usage changed, Do you mean its using more or less DEF? Do you notice any change in your fuel usage after the update?
