2014 Silverado 3.42 or 3.73
Hopefully some of you have a bit of experience with the newest GM trucks? As a bit of background. I have towed a considerable amount in the last 15 years, with roughly 1/2 dozen TTs and almost as many...

You will be sorely disappointed with the power and fuel mileage, the 5.3 will be barely enough with the lower gears pulling that trailer. You are pushing the limits, it is at the top end of the range for a 1500. We made that mistake with our first combo, it took all the fun out of rving particularly on steep grades.
I could not disagree more. The 2014 5.3L has almost identical power to my 6.0L and similar gear ratios. My TT has a yellow sticker weight of 5500 pounds, so I estimate loaded at 6500-7000 pounds depending on what trip we are on. My truck tow my TT easily and so would a 2014 half ton 5.3L with either axle.
I always recommend the shortest axle ratio. There is no measurable difference in fuel consumption, but always a noticeable power difference. But the 3.42 is plenty for that TT. Use Tow/Haul mode, and M5.
6-spd with 3.08 is very close to the old 4-spd with 4.10 axle. 3.42 more like 4.56.
