Look at my hitch set up please....

Is that why when a tractor trailer passes me on the highway it sucks me right in?

The lower air pressure and air movement created by the moving tractor-trailer is the force at work. It is likely that your hitch has little effect against this force.

I'd suggest that the hitch coupler replacement be done at a qualified trailer/welding shop. I wouldn't trust a dealer's service or repair facility with that task. BTW, if your brakes and bearings haven't been inspected and serviced (even though the trailer is new), you may wish to have that done at the repair shop. There have been more than a few stories about inadequately greased hubs and maladjusted brakes with new trailers on this Forum.
