Do you notice the porpoising most on concrete roads with expansion joints?
There's nothing you can do about that. It's a function of the road vs. your truck's wheelbase, neither of which can be changed easily.
We have a couple of stretches of road around here, the last 5-6 miles of the East end of Interstate 490, and the NYS Thruway between exits 40 and 39, that my truck just gets to GALLOPING on if I try to drive below 65MPH.
I'm talking wheels leaving the ground, bucking-bronco, thank God for the seat belt or I'd be banging my head on the roof, dolphins on meth porpoising.
