Thank you

Hey everyone, New to this forum and have come here for some insight. I have a 2014 GMC Sierra 4x4 5.3L with 3.08 gear ratio and 265/70R17 tires. I live in Maine and do a lot of towing with a 4500 pound trailer. The state has lots of hills/mountains and I find my Sierra constantly downshifting/hunting for gears on the highway. I'd like to change my gears out to 3.73's or 4.10's. Right now with the 3.08 traveling at 80Mph I am at around 1850RPM. If I go with 4.10 gears and keep the stock tire size what RPM will I be running at 80Mph? Would 4.10's be too much, or should I go with 3.73 gears? Not looking to go with larger tires. Thanks, Josh
