You said a 4 ft rack off the back. If that rack is loaded down, it will lighten up the tongue weight and could be the cause of the sway. Tires and tire pressure could be part of the problem. Don't get the Hensley until you figure out the sway problem.
Agreed on both counts.
When getting the rig weighed, he should have the rack loaded as if going camping.
Also, regular non-towing pressures will lead to tire "squirm" which can be confused with sway - they are not the same - which is also unsettling. For my truck I have to have at least 40 psi before I have no squirm. I tow at 45 psi. I have no need for anything other than the standard P grade tires that came with the truck but when I replaced my factory tires (due to wear) I just gor XS passenger tires and they are better than stock and adequate for the job.
