Highway, no. When cornering, let off the gas unless you enjoy getting jerked around. I've discovered two ways to take a slow corner (not one you'd take at highway speeds). Either ride the clutch through (if you have one) if you want to give it gas and accelerate through, or keep your foot off the gas until the turn is complete (your out of the turn and going straight) and then you can put gas back on.
If you drive your truck like a truck and not a hot rod which 90% of truck owner here do your will be fine. I get the tire scrub round sharp corners but nothing bad
