Torklift Rear Tiedown on 2017/2018 F350 OEM Hitch?

I just installed these F3008 on my '17 350.
Took about 10 minutes and are very stable with a load. I started with the 'bumper buttons' but, the bumper moves too much and I lost the turnbuckle on one side so I opted for the Forklift ones and am very happy.
They slide into your hitch open ends and one bolt. Viola, you are done.
The front ones (F2021) are more of a pain and took about 3 hours. The whole package is very stable and the camper stays put!
