2500HD ride
I have a 2012 2500 HD Cummins Diesel GMC and tow a 10,000 lb bumper pull. I have added two leaf springs on each side of truck. What can I do to improve the bumpy ride while towing the trailer?

Hmmm...... my older '03 2500 Dodge/Cummins quad cab has LT265/70-17" E tires.
I've found this trucks front tire work best with 65 psi in the front regardless of weight on the rear axle such as my 11200lb 5th wheel trailer....a 14k and 16k GN trailer.... 10k bumper pull trailer.
With a empty truck I run 45 psi in the rear tires. My 5th wheel trailer adds 2200-2400 lbs on the rear tire and 70-75 psi works best for these tires.
The 16k GN triaxle trailer hitch load is close to max rear axle/wheel/rear spring pack loads so I use 80 psi in the rears.
My 10k car hauler can have different equipment on it so hitch loads can be 1800 lbs or sometimes 1000 lbs depending on how everything is placed on the deck.
Why the extra springs with just a 10k bumper pull trailer ??
If the truck is pogo sticking in the rear then new shocks would be a good idea.
Extra Springs/bags can be a butz kicker with certain sizes of trailers.
