Ride height variation

I’ve got an 2018 and planed on installing one of the Icon lifts but not enough cash to go around so I’m considering the 5100’s to level and get what I can out of it allowing for a little larger tire. I checked all four corners and the trucks low on drivers side both front and back 3/4” compare to the passengers side? I’ve put 75,000 miles on it in less then two years, is it possible the difference is just my weight driving over the past 23 months. thx
