You will get many answers even ones you didn’t even ask. Here is the truth unless you want to blindly go by the door sticker.
Load your truck and RV with everything!!! This includes fuel and passengers.
Go to your nearest truck stop that has CAT Scales. Weigh your trucks front and rear axle then each RV axle.
With these weights you can PROPERLY inflate ALL your tires.
Look up the tire size and load range weight/inflation chart for your tire. For the front tires add 10psi to what the chart says the psi should be. For the rears add 5psi.
You will get the best possible tread wear, traction and ride when towing.
Solo leave the fronts and reduce the rears to 35psi.
