I had to do the same when I was running OEM rated tires to avoid going over the capacity in the rear. After a few trips, it got old keeping weight properly distributed since each trip we seem to take different toys with us. My solution was to increase my wheel ratings so I have more flexibility in loading and now I have more capacity than weight I want to carry.
I'm sure you you can add cargo boxes aft of your axle to carry heavier items which will help your front axle weight. I know my next truck will have the heaviest available springs up front allowing me to carry more weight mid wheelbase and even go to a heavy front bumper/guard.
Is your front axle actually rated for 6830 lbs or is it rated for more and the suspension is your limit?
