Does anyone have any experience with these?  Questions?

I'm not familiar with this product , But I do have a HiTie, which I really like

I frequently camp where there are No trees, so no Highline. My horses have spent many a night tied to my trailer.

I sleep a lot better with the HiTie than I ever did with the horses tied to the tie rings.  Not near the jerking or tugging.  Plus the horses have a large area to move about in.

Caveats.

The roof on my trailer "Rolls over the side"  So if I mount the HiTies as high as the flat side allows, I'm not as high as I would like.  I also wanted to mount mine with the bolts through a metal stud in the wall. Not just the aluminum skin. Since the metal studs are only every 16" or so, couple with windows etc. The location of my two HiTies is a little closer to each other than I wanted.  If I leave the ropes long enough so the horses can feed off  the ground. They can also twist around each other. I wish I had spread them another 16" farther apart.
