I am not towing a large travel trailer but I would take my 3.08 equipped grocery getter over the towing 3.42’s any day unless I was going to be towing at the limits. On a recent non towing trip on two lane roads at 60mph I was pushing 29mpg. Memorial Day weekend with eight of us and a roof top carrier I was getting over 22mpg on the highway. I never saw those numbers with my 3.42 equipped Yukon XL. The Suburban also gets 2mpg better towing than the Yukon XL did.
I also have a 2018 Suburban Z71 (4WD) with the 3.42 diffs that gets about 22 mpg on long trips. When towing my 4500 lb travel trailer, i get about 12 mpg with the 6 speed tranny set to manual 5th so it stays on V8 all the time. I don't use the tow/haul on drive because it still shifts to 4 cylinder which is not good when towing.
