Tying the rear frame rails together? Opinions please!!!

I considered that when I did mine with 2"x3" stuctural box steel with .080 walls.
The problem was that it looked like it couldn't be a straight shot from side to side without having to go over or under something.
I thought about a driveline loop to get from one side to the other also, but didn't do it because the connectors themselves made such a huge difference.

I couldn't bring myself to pay what they wanted for something that looked like it came out of a swingset kit so I made my own.
