Got a new truck do I need an upgraded hitch?

[Doc Foster]

I just upgrade from a Toyota Tundra to a Ford F250 Diesel, and it sits 3" higher. It doesn't appear that I have 3" of adjustment in the hitch bar, maybe 1/5".
But it is a bit more complicated than that:
I started out with a 19' SOB with a weight just under 5000 lbs loaded and towed it fine with my Toyota Tacoma with a Reese Trunnion Style WD setup with 800lb. bars.
The Tacoma was ruined (whole different story) I traded up to Toyota Tundra and eventually a 25" Flying Cloud. I kept the same hitch but they recommended to upgrade to 1200 bars.
Then I upgraded to a 30' International that same hitch setup worked fine last year, but this summer I seemed to get a bit of sway sometimes, particularly on grades and when being passed by big rigs. I had the cheesy friction style control for the whole time. Plus the Ford F250 has those reducer sleeves in tow hitch for various size hitches, and I am concerned about slop in those sleeves.
Sorry if I posted this in a confusing manner.
Any recommendations are welcome.

Why would you even ask? Buy a HaHa or Propride and get back out there. Pat

I sometimes pull a 32' Airstream. The first time I pulled it I used the same bars and setup as I did for my 25'. It did not feel real solid. I could upset it at 60 and get just a little wiggle. I went to 1000 lb bars and re-adjusted the hitch. It now seems very stable and solid. Sounds to me like you need to re-dial in the hitch for the trailer. And if the trailer is at all nose up or heavy in the back that is a bad thing. And careful when you switch bars the 1000 lb bars I got are slightly longer than the 800 lb bars so you have to re-adjust the trunions on the Straight Line hitch.
