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...
How did you load your TT for this trip? Did you put alot of stuff aft of the TT wheels or hanging on a rack off the bumper? That would do it. I have the Reese dual cam hitch with the same bars for 12 years now. I still use 6 links of chain on them. They havent worn out. Examine them and maybe you cracked one or the hitch is defective in some way. Otherwise I think its your load.
