Going up hills
I'm new at rv-ing. Just bought a 24' Forest River EVO TT; I have a 2012 Silverado 1500 4WD Crew Cab short box. It has the tow package, Model K10543, 3.08 gear ratio, 5.3L V8. I I'm getting air bags in...

I would change out those 3.08's for 4.10's or 4.56's.
Wholly unnecessary.
Silverado 1500's with the 6-speed come with AT MOST a 3.73 axle.
The 6-speed makes the truck tow like it has one to two full gearing steps shorter. A 3.08 tows like it has at least a 3.42. A 3.73 tows like it has at least a 4.10.
Real world experience here. My daily driver is a 2015 Silverado 1500 with the 5.3L and 3.08 axles. It tows a 4000lb SO much better than my old daily driver did, with 3.42 axles, almost as good as my dually. The old truck couldn't hold overdrive on the highway, and needed to drop into 2nd more often than I would like, while this one rarely shifts out of 5th.
