I pull a trailer at just about the weight you are looking at with a Ram 6.4 gas engine and 3.73. We do great; flats, hills and mountains. Diesel would give us more oomph and a 4.10 makes it a little easier but I've owned both. 4.10 is generally hard to find whereas the 3.73 is kind of a "go to" ratio. I wouldn't worry for a minute if all you can find is the 3.73...btdt.

I WOULD worry. There is a big difference between the 3.73 and 4.10 specs from GM. I can't find the exact 2011 numbers, but they were pretty close to the 2019 numbers. These are the 6.0 gasser numbers. The numbers vary a little based on 4WD or 2WD, Cab, etc.
3.73 Max Trailer = 9,600, and GCWR is 16,600
4.10 Max Trailer =13,000 and GCWR = 21,100
Wouldn't be too hard to exceed the limits of the truck with the 3.73 with a big trailer.
You gotta pay attention to what GM says.
