Frame flex??

So I had my lovely girlfriend get out of the truck and take a video of me driving up this pretty tricky hill. Later after watching the video I noticed how much my bumpers flexed when crawling over the bumps. I'm assuming this is normal? I'm starting to see a few marks of the bumpers rubbing on each other but nothing to serious yet. Let me know what you think!!?

 

Completely normal all truck frames will flex when you twist up like that.

 

My new 2016 has uneven gaps almost as bad as the picture only about 3/8" of difference. My truck has never been offroad and surely has not been hit...theres not a scratch on it. Are these adjustable? Just looked at it and shook my head...factory didnt check for alignment?
