Another Bracket Search

You folks helped me find the other bracket I was searching for, so I figured I would ask for some help again.

I have been all over Camping World, Tweetys, PPL, and various other trailer parts websites, and for the life of me, I can not find this bracket.

I either am searching in the wrong place, or looking for the wrong terms.

Does anybody here have any idea the correct name of this type bracket and where/if I can find one somewhere?

Thanks,

Jerry
