Backing up a steep driveway in 4WD Low gear?

Hi folks. I'm looking for advice on whether I can, or should, use 4WD low gear to back up my 25 ft. Microlite (7k lbs.) in low gear with my 2017 Chev 1500 5.3L. The standard reverse gear seems kind of high, and I've gotta back up a pretty steep drive, concrete, with a 90 degree turn on the drivers side onto the driveway and a 90 degree turn to the passenger side on the top after it flattens out. I'd like to take it slow, but don't want to put bad stress on the drive train either. THanks for any help.
