Hitches and Sway Control
I think the hitches are all pretty much the same. Drawtite, Reese, etc. all seem to have pretty good quality. I did have one Drawtite that had little spring loaded pins on the backside of the torsion bar holes in the bumper connection that kept falling out. Had to be careful how far you pulled them out to drop the torsion bar out of the hitch.
The sway bars work good too. I think the main thing is proper alignment. The reason you use a torsion bar hitch is to evenly distribute the load. When you first hook up the trailer and let it down the front of the tow vehicle will raise up. The torsion hitch puts the front of the tow vehicle on a level plain and the combined units should be level. So you have to adjust them with the chains and hooks or whatever design the hitch uses.
I was towing a 24' Starcraft with a 1/2 ton Suburban and had to purchase a torsion hitch. Someone had stolen my 3/4 ton GMC and I didn't have to use a torsion hitch on it. Anyway, the instructions said to park it on a level surface measure the difference from the bottom of the front bumper to the ground and then do the same with the rear. Then you had to hook up the trailer and raise the rear of the Suburban up with the jack and hook up the chains. When I let the jack down I had to measure the front and rear distance again. The instructions said there should be no more than 3/4 inch difference with the trailer hooked up. Mine was at 1 1/4" so I kept working on it. I moved shims in the hitch, hooked it up another link, etc. etc. I couldn't get it within the 3/4" difference. I finally called the manufacturer for advice and the technician about laughed his head off. He couldn't believe that I got it that close.
Anyway, I pulled it for a lot of years without any trouble.
Then I bought a motorhome. That is a whole different story.
Good Luck and Happy Camping
