Make sure your tie downs are adjusted properly. I usually drive about a mile and recheck after loading.
Next if you have not upgraded your shocks you will in all likelihood get some oscillation or some refer it as porpoising..
Also check you tire pressure 80 in the rear, unless you have a dually and about 70 in the front, unless you have a diesel.
I have 70K miles on my SHORT BED and I do not have any problems with oscillation at any speed or road types.
The other thing if you slowed down to 60 maybe you driving faster than road conditions dictate.
My tie downs were installed at the dealer. How do I adjust them "properly". I have the torklift mounts and fast guns.
