Tire pressure - please confirm

If the sticker on your truck says to inflate to 35psi, then at 35psi your tires would be capable of carrying what your truck is specified to do (GVWR, front and rear AWR).

In theory you could set them at 35 and forget about it.

When towing I do tend to increase the psi and then decrease it after the trip.

Same here. It takes me a few days to remember to drop my tire pressure. Usually driving over an angled railroad crossing will give a real quick reminder when the back end of my truck bounces sideways lol

I don't have Nitrogen, but on my 2012 F150, I run 35 when not towing and increase to 44 (Max) when towing.
I run the original P rated tires, so the added pressure stiffens the sidewalls.
When we park our TT in a campground and drive the truck, it has a very hard ride with the extra air pressure.

If you have Passenger tires instead of Light Truck Tires, you will want them as firm as possible while towing. Before switching to LTs, I would inflate to 44 (max sidewall) when towing, then deflate to 39 (recommended door pressure) when I was done towing for a while or for the year. Now with the LTs, I will probably still do the same procedure, just to make the ride smoother.

Tire pressure should be set according to load they are carrying, as such when you are not towing it is fine to adjust psi for a comfortable ride. When planning to tow, for better handling and to increase tire's carrying capacity, psi should be set for added weight of RV or to max psi as stated on sidewall. We do the same thing from time to time, our TV is dedicated to hauling our TT around and most times psi is usually at or near max psi.

What size tires? What load rating?
Lower the pressure to 35. You certainly won't hurt anything when not towing.
When towing you might need a higher pressure.
