OK, so with all of the feedback in here, research, and talking to the best RV guy, I think I’m getting clearer.
It would be better if I towed my four horse stock trailer with my Surburban with a WDH so the back of the Burb doesn’t drop. I really have no issues with sway control.
RV guy says all of the hitches are pretty solid. I watched the videos a bunch of times and think I can actually do this on my own, making SO help me. I see the big issues is getting bolts undone.
Amazon is an easy way to go because I can get it within 3 to 5 days. Some are about the same as other sites, some are way more expensive.
These are about the same on Amazon, and I have my own ball:
