Home made Rear bumper questions and suggestions

I made my rear bumper using 1/4" plate and thick wall square tubing. I used the Comp 4x4 hinge kit for the pivot and I also have a locking pin that you can see in one of the photos.
I seem to get a lot of movement that I can see in the rear view mirror while on the freeway. I have two rubber stoppers that press against the tailgate to preload and take away some of the bounce. Look at the picture of my latch.....the main carrier bar rides on 1 rubber stopper when closed, but the pivot is beefy enough to support without this.
I saw someone with an LOD carrier on the freeway the other day and that thing was bouncing like crazy. Am I expecting too much? Does anyone have a Garvin carrier that could tell me how much it moves?
Should I fabricate some type of block at the latch to support the main carrier bar? Are my stoppers too cheesy?
I don't see a lot of JKs with the gas can setup. This was how we all rolled with our TJs in the club I used to be in. Is there a reason for this? I know these JKs are not a tub body design so does that cause more flex and rattling around of the body? When I made my side step rock rails, I thought I had left enough room between the bottom of the Rubicon rail and the top of my rock sliders. When I went over any bump I would hear a crazy rattle so I had to grind down spots on the Rubicon rail.

NavyDave,

Where did you find your hardwear for this build? I am looking to start making one myself but am looking to order the pivit portion and hing lock. Any help would be great.

Side note where in Cali are you stationed? I spent 9 years in Oxnard CA when I first joined.

I'm out now, but I was stationed at Pt Loma Sub base San Diego
I used the comp 4x4 HD pivot I bought online. As far as the latch, it is a destaco clamp with stainless steel u bolt
