Sway/Reece dual cam issue with a F250

Don't let me steer you wrong incase something else is causing it. If it's a rhythmic fishtail that gets worse with speed, it's sway. If it's wallowing all over your lane, it could be tread squirm with soft tires or all terrain tread. If you're feeling trucks pass, especially box trucks, busses and motorhomes, or gusts of wind while passing tree breaks, you might not see much improvement from one hitch to the next. We didn't feel the push and pull of side winds with our 5th wheel. Once I got used to it with the travel trailer, I just ride with it and it doesn't bother me. We get pushed around more in our car. Everyone is different and yours might be felt more than ours.
