Great job on the Hensley, your going to love it.
A few things I've learned....
Run your 7-way cord thru the d-ring pin for the tongue latch.
Attach the breakaway switch somewhere other than the hitch receiver, some have used a ring attached to a license plate bolt.
Secure the 7-way plug with a zip-tie, ask me how I know.
A "hitch'n rod" with an O-ring is a quick way to get the height right.
Your rig doesn't appear level, TV high in rear, AS low in rear.
Too much air in the air bags?
Remember the bags don't increase payload, they only level the TV when bed is loaded.
Iv'e found with ours that the rear-end droop is taken care of with properly adjusted wd bars.
Have you been to the CAT scales yet to properly set weight transfer?
