frame flex with anti sway bar

Ya really think so? Does the body of a uni-body vehicle flex? Have you ever ridden in a citron? I may stand corrected, but I think they are uni body. It has been many years since I have ridden in one, but the ride was as smooth as it gets.

I am not sure what wedge your referring too? The tailgate had no issues, as I had to let my dog Cooper out.

That was a fun day. Six very full loads of sand for the dry lot.

You are not showing close up, but looks like the gap between tailgate and right side is bigger at the top, than at the bottom. That is sign of flex.
Other is comparing space between top of the bed and cabin on both sides.
Wait a minute, isn't the space the bed and rear glass a wedge?

Dump trailer with a very full load of sand. This is with a big wig sway bar installed.

Yes, it will twist. No, it's not bad for it.

Sorry, I was just posting that as an example of frame flex or frame twist. I definitely don't want to turn this into another truck bashing thread. I like the Ford a lot, especially the motor and trans.

It is favorite competition sample, that Fords, when lifting rear wheel off the ground often are developing tailgate bulge due to frame flex.
There is flex to everything. Golden Gate bridge flex under full load several feet.
Coming to anti-sway bar, they transfer relatively small power, just like weight distribution bars, or even less. If you have to worry about flex due to bars, than you have bigger things to worry about.
Lately I noticed that anti sway bar on wife Mercedes is thicker than the one on my F350 dually..

hmm.....

Yes, it can add frame twist just by the fact that it tries to eliminate axle articulation. Your truck however should not have any frame flex since its a boxed frame and designed to be rigid.
