2018 Ram 2500
At present am towing a 31foot 5TH with a 20016 Chevy 2500 HD 6.0, 6sp, 4.10 gears. Was looking at a new Ran 2500 6.4L and noticed that the truck has coil springs on the rear. What are the advantage/d...

My friends have an 07 or 08 Ram 2500 Cummins that has a "light load" button that allows them to run lowers pressure in their tires with out the computer nagging them. Are the newer ones not like this?
Never heard of that. Maybe an upfitter or aftermarket option?
No, it was a factory option. Not entirely certain why they got rid of it, but I'm sure it has to do with liability. I'm sure some idiot was running the light load setting while hauling weight and had a tire failure and sued.
Its odd that Ram demands such a high PSI for the rear tires, with such an artificially low payload rating. My truck wants 80 PSI on the rear tires. With factory 18" tires, that's a combined 7280 lbs of load carrying capacity... more than the factory coils are rated to carry and much more than the artificial 10,000 lbs GVWR will allow.
