I’m running a 2012 3500 crew cab with 3.73 gears I get around 12 mpg towing my 16K lbs fifth wheel. Running around town empty combined city/hwy I got 18mpg on my last tank. I rarely go more than 65 mph because of the drop in mpg’s.

air bags are probably the best way to go as you can adjust them for how the truck is loaded. I've driven 2 trucks with the Timbrens and the best improvement was removing them.
