Post maiden voyage, deciding on modifications?

I would first get it weighed loaded for camping and full of fuel, water and whatever else you would carry when camping including passengers. Get weights by axle. Then go to the Goodyear or Michelin Tire Inflation Charts to see what psi is recommended for that weight for your tire size. It will probably be different for the front vs rear tires. I have a 2013 F350 Dually pulling a Jayco Toy Hauler with a approx. 3500lb pin weight. I run 60 in the front and 65 in the rear tires.
