He has E rated tires, they certainly aren't passenger tires!
And E rating is not "stock" for that truck.
If OP is following inflation chart on the truck door post and is running LT tires rated for E loads, that chart is invalid as it will give them too low of a pressure.
That truck was equipped with PASSENGER tires and as such will have typical passenger tire pressures.
The tires in E rating will require MORE pressure than P tires to get the same weight rating or higher than P tires.
E rating tires to get max rated capacity are rated at 80 PSI, Passenger tires typically will max out at 35-36 PSI..
35 PSI in LT E rated tires would be considered as having a flat tire..
Too little air pressure in those E rated tires can easily give you an odd feeling of being pushed around..
OP should have gone with LT tires with C rating which would have given them some extra weight capacity over stock P tires and would be a much better match to the vehicle.
E capacity is too much overkill and potentially part of the problem they are having. And yes, you CAN have overkill on tires.
