Turnbuckle ?

I have always been old school using TL original spring loads, turn buckles and chains. The camper tends to stay loaded on truck for months so the turnbuckles have never been an issue.
I do however have a full set of HJ original spring loads that I have never used. I dusted them off tonight as I was setting up the new truck. I have to be honest; I don’t see any advantage to these versus the chains/turnbuckles.
Seems to me these would be just as much work (rotating to achieve proper tension).

Am I missing something?

Who’s using HJ originals? Who’s using original TL’s?

Thx, Bill
