When I bought my truck over a year ago. I went with the 3.21 hoping it would give me even a little better mileage, and I also did not anticipate the need to tow more than ~5,000 lbs. I believe my tow rating is 8190 in the current config. Now my family is looking at travel trailers, and we need sleeping and elbow room for 5 people minimum. We can get away with 28/29 footers, but my wife wants a NICE trailer. That usually means more weight and I'm not finding many options that leave much room under the 8190 lb rating. It's close though and there are a few options out there, but there would be more options if I could tow the 11,000+ lbs of those trucks with the 3.92.
So my question is, does anyone know the process and approximate cost to upgrade from 3.21 to 3.92? I really like my truck, and don't want to swap the whole truck out for a different rear axle.
Thanks
