Have the truck now. Door sticker says 60 psi in the front and 80 in the back. Tire shop that swapped my tires onto the new truck did 55 and 70. On smooth pavement it rides pretty well, only a little worse than my max trailer tow F150. On rough pavement it skitters and jitters around and makes me slow down some. I'll have to reserve judgement until I get my topper back on.
Front axle #5000, rear #6730.

You swapped the E tires from the 1/2 ton to the new 1 ton...got it, must be nice tires.
Truck is empty now, but going to put a topper on it, rear tires at 70psi and it skips on rough pavement bad enough to have to slow down...makes sense since its too high of pressure.
Reserve judgement for what? 6730# rear axle? Rated weight I presume? Since if you had 6700lbs on the rear axle now it wouldn't skip around.
So drop the pressure to 35-40 psi in back. How does this even sound right if the heavy front end has less psi than the light rear end and you're waiting to add the equivalent of 10 bags of dog food (the topper) to see if double the tire pressure you need will feel good?
THIS is why mfgs put TPMS on passenger vehicles, to save people from themselves who can't even conceptually understand the relative weight of objects.
