Rails suck. They are obsolete technology. Do they work (and work well)? Of course they do! But there’s exactly ZERO reason for anyone to go back in time in favor of obsolete technology. Plus, there’s exactly ZERO guarantee that a newly purchased rail system will match the existing holes from an old rail system. How do I know? Been there, done that.
Here’s an article warning of the same issue:

I’d much rather put that brand new 4” hole in the middle of my bed and get the best hitch combo option available vs. trying to maybe re-use some old holes that might not work and is regressive technology.
I’ve used an AUH aluminum and had no trouble with it. The friend I sold it to also has no trouble with it and he uses it for more than just RV towing. There’s nothing wrong with that product or the idea of a single point attachment.
