Great idea for a topic, Bill!
Just got these today. I hear that these'll help keep my camper near my truck, so I got a couple of them:
And I heard that a lot of guys accessorize theirs with nuts, so I added those, too.
[Why two different designs/styles?
Well...Ace Hardware (the only place in Bend where I found appropriate turnbuckles -- not even Home Depot and the biggest RV sales/service place had them) had both of these on the same peg, and the labels on them had the same specs. The square-edged one looks identical to the ones that came with my FWC Hawk, but it was the only one like that on the peg. And since I needed two of them I had to get one of the other style, too.]
