I run with the tires at the PSI recommended for the truck on the door plate and not one pound less. It reduces flexing of the sidewalls which improves control and minimizes heat buildup in the tires and less chance of a blowout.
Porpoising comes from not having enough load support at the rear wheels. Easy to fix with leaf springs and more limited with coil springs where there is not an overload support. Airbags are better than nothing but they also contribute to porpoising.
With inadequate load support at the rear wheels the shocks will be less effective and will wear out sooner. I like the Rancho adjustable shocks and will increase their resistance setting when towing.
I added a Hellwig Big Wig anti-sway bar and it did nothing for the handling of the truck with a 3500 load in the bed or when towing a 13,000 lb trailer but it did dramatically improve the ride when the bed was empty and no trailer in tow. Far less wheel hop in turns or when hitting a bump with one wheel as the force was distributed to the opposite wheel with by Big Wig.
