I may be stretching the effect the sway bar has on smaller elevation changes. The rear of the truck felt really "locked down" and seemed very harsh on city street bumps.
I had back surgery August 21 and our local small town streets are beating me up pretty good. I just didn't remember the truck being so rough riding before the surgery. But, I had a month of not driving it. I've backed the rear pressure down to the high 50's and it helped some. A couple days ago I aired them down to 50 and backed off the fronts to 60. It helped a lot. I'll keep tweaking it. I'll watch the edges of the tires for wear.
