Too much weight for a truck with that rear end. You will burn it up if you hit the mountains. Trust me, I know that from doing it. 4,500 lbs is almost too much for that to pull on a regular basis. You have the weight plus the wind resistance going against you.
If it was an older Tahoe with a 4-speed, maybe. This is a newer model with a 6-speed and 3.42's, as good as an older 4-speed with 4.10 gears. It would only burn up if it had inadequate cooling. It does need the tow package to have adequate cooling.
