Well Terry.. No disrespect meant.
When I bought my 2010 Keystone and the guys at the dealer setup my hitch whom do it for a living, I had the same problem as the op. The dreaded V on a brand spanking new Ford F-150.
The hitch was setup properly but it needed more Springs or air bags. I chose air bags this time and it worked perfectly with this trailer and others I pull on a regular basis.
The opp asked if anyone had tried them and what they thought, having had the exact same problem as he has, I replied yes they work and my WD hitch was setup right.
Another or different hitch would not have solved my problem.
Have a nice day.
