Lets get this back to basics...
Get out your bicycle...
Fill the tires to the maximum pressure on the side walls... pedel it around the neighborhood including over some rough patchs of road and up a steep hill.
Now drop the air pressure to the point where the sidewalls on the tires are squishy... it takes a lot more of your personal horsepower to peddle it even though it isn't so bone jarring in the rough road portions.
It's a little harder to control when the tires are squishy, the sidewalls bulging
Now, take a look at your truck with the camper loaded for your trip... are your sidewalls bulging?
If you have a duallys is there a danger that the tires will touch, building up heat? Is there a danger that rocks might get wedged in between the side by side tires?
Think about your bicycle... is your trucks engine and your mpg (energy) going to benifit from the maximum air pressure in your tires for 99% of the roads you'll be driving on?
As I've said before... I am happy with 80 PSI all around... and the 15 mpg, stable ride.
Hope you enjoy your trip.
