This is pulling large grade in NCaroline up the smokies with a 5.3 pulling 5500 lbs trailer fully loaded. I dont floor my truck ever. I let the engine work.
1st gear 30 mph and 3500 rpm.
Infact I take my foot off the gas some to keep at 3500 rpm.. Remember I have 4 speed..
Notice engine temps 230f but trans temps with cooler 175f or so.

And this is 2nd gear trying to pull highway grade. Im trying to not let it go into first gear.
30 mph and 2200rpm. Second gear is a dog if you don't get momentum for the hill. But there is nothing you can do. I couldn't speed up.. I could just maintain..
Imagine if I towed 7500 lbs as Chevy says I can??? LOLOL ha ha ha

Lugging at 3500, you’re leaving a lot of HP behind. Spin that motor up a bit. When they spec the tow rating, Chevy probably assumes you’ll actually let the motor run instead of holding back on the go pedal.
Hardley lugging @ 3500 rpm. Im right in the torque band. Why gas it up and rev to 4000 to go 5 mph faster. If I let it shift to 2nd it will dog and kick back to first anyway..
I wasnt struggling in that first video. I was just letting the engine work, and that was a comfortable RPM and speed for me.
Since the 4l60 trans has such a low 1st gear I can pull any grade with 6000 lbs on the hook. Not fast but it will do it.
But as in the second video I was lugging there a bit. It was an in between 1st and 2nd gear thing... Oh I wish I had a 6 speed, but it is what it is...
But to the OP, you will be fine IMO.
