I run what the truck calls for on the factory tires. 90 in front and 80 in the duals. I would not run them lower as the stiff sidewalls likely would not be happy. I would like to find some load rated tires with more squish or that reach an expectable load at lower pressure. Then maybe some squish to help smooth our the road joints and potholes.
Again, hence my comment about not thinking about this right...
You want to "upgrade" to a MUCH heavier duty truck, which like your 450, has 19.5 wheels as the only option (save for 22.5s or a VERY custom setup with...whatever).
If you want "load rated" tires that will handle your camper AND have softer sidewalls, you reasonably have to move DOWN in truck class to a class 3 1 ton with LT tires.
And as I mentioned, you also haven't looked to see how low of pressure you can run for your load. But if you do, you'll find that with your load, youll be able to lower the pressure a bit from where you're at.
