[Retired Copper]

x2 on the other`s post. Been right where you are at now. My first step; if a new truck is out of the question, would be the hitch and I too like my e4. It made a difference I could feel and I have never had it to sway as of yet, but it important to set it up right. That being said it doesn't keep you from getting pushed around sometimes. Second would be the tires, P rated just don`t cut it. The third thing is shocks; adding a sway bar might help. Trailer tires helped me by going a load range up and having them balanced. My F150 with the 355 gears pulled the trailer pretty darn good but it too was about at the limit with a trailer a little longer and about 800 lbs lighter. I found that anything over 60 to 63mph the truck would get a little loose under some cross winds or some speeding semi`s. When that happens it surely will wear you out or at least it did with me.
