We have a 32' travel trailer which we pull with a ford e 350 diesel. We have reese sway bars. We have traveled all across the country with no issues. Today we have been swaying like we were on a dance...
I just replaced my suspension equalizers because they were noisy. I went with Dexter EZ flex. What I found was that everything was worn out. All the bolt holes were oblonged. Basically the trailer was walking over the axles. After I replaced everything the trailer handled so much better. The trailer always felt loose behind the truck. Now the whole setup feels more stable than it ever has. Check out my posting in the Dexter EZ flex sticky at the top of this forum.
