Here is it loaded using the next shorter chain link. Lots of tension on it, and has raised truck a little higher than without trailer.

Not sure if pic is viewable, but bars are loaded and bent.
The trailer frame is strong enough, and Class V hitch won't know its there. More concerned just about the receiver and WD components related.
Not worried about the ride, or the other details, just the safety of the system.
I could tow trailer without any WD help, but rather have weight of truck…
Thanks for other related comments, but Im just looking at how much tension goes into this and thinking, wow, thats a lot of stored energy…
