5 weeks into our 4 month trip from Florida to Colorado and back via Connecticut. Towing a Grand Design 2600 rb TT which is approximately 7200 lbs gross. No problems with towing thru the steepest mountains so far.
The smart E brake mode is awesome. Makes the downhill hairpin turns a piece of cake.
I don’t push the truck I take it easy and stay under 60 unless I need to pass something.
So far after about 3500 miles which includes non towing excursions I am averaging 16.1 mpg hand calculated.
Very happy with that even though every towing day is around $100 worth of diesel.
