80 PSI up front sounds like you are asking for a harsh ride from over inflated tires. I use the tire inflation tables based on actual weight to pressurize mine. I find the front changes very little whether loaded or empty and is never at the weight that would require that much capacity at maximum pressure. What's actual front axle weight 5000-5500 lbs?
80 is NOT a lot over what the load dictates. My front axle is 5,480# every day and loaded 5,640# . Door says 80 but the fact is running lower will cause outside edge wear. What i have found running pressures based on load is adding 5psi to rears and 10 to fronts based on actual load to what the charts dictate. I have gotten excellent wear by doing so.
Take my front axle weight divide by 2 = 2,740# that would require a minimum 70psi based on the chart. Like I said for the front axle add 10psi that will give you full tire capacity of 3,085#.
Run the tires at 70psi and report back showing the edges are wearing faster than the centers.
BIG deal OP is get the truck in right away and have the toe set to 1/32-1/64". Don't do it then come back in 5K and ask why the outer edges of the front tires are stepping. RAM has 1/4" as their toe spec, that is to keep the truck tracking straight. I rotate fronts around 15K.
Run the pressures MeAgain recommends as those are what I have been doing with great success.
I never touch the rear tires I only rotate the front tires side to side with the rotation going the same. They have to remove the tires from the wheels to do so. I have them keep the wheels on the same side as they were.
This will give the best tire wear and ride.
Ya want a softer ride get a 1500!

Caster is what makes the truck. To much toe will make the truck follow the road imperfections and make the steering wheel off. The more toe in the sharper the truck will turn at full lock. 1/4" is not bad (1/8" each side). I like to run my trucks with 0- very very little toe in.
