Well I played with this for days.

Either the weight on the truck axles is within specs with the truck and camper not quite level,

or

the camper and truck is level and the weight limits are/is out of spec on the axles.

The truck
Steer Axle 3200
Drive Axle 2440
Gross weight 5640

First scale weigh with trailer on hitch
Steer Axle 2960
Drive Axle 3340
Trailer Axle 4600
Gross weight 10900

The weight on the rear should be between 2966 and 3329.

Latest scale weigh after moving hitch head up and down, back and forth.
Steer Axle 3000
Drive Axle 3280
Trailer Axle 4660
Gross weight 10940

The bars a slightly raised up not quite level. The fifth ring of the chain is on the hook.

The rear of the truck sagged just about an inch, the front raised 1/2 inch.
To the eye, the truck is sagging and the trailer is dipping forward.


One last adjustment I will make as some mentioned is pushing the hitch head back a notch.

Friday is depart day. NC to Wyoming or bust ... If anyone anyone has any further suggestions, Im all ears. I guess the question is, is it better to have the weight right or the "levels" right ... or the closest you can get to a happy medium.

PS ... On all of the other trucks Ive had ... Rams 03, 05, 06, 09 ... this 12 has been a hassle to setup ... One reason I believe is the change to coil springs. Should have kept my 06 Mega cab SLT !

On your "First scale weigh with trailer on hitch", the steer axle was 240# lighter than unhitched.
On your "Latest scale weigh after moving hitch head up and down, back and forth.", the steer axle was 200# lighter than unhitched.
Whatever you did between "First" and "Latest" had little effect on the front axle load.

I suggest you continue to increase the rearward tilt of the ball mount until the front axle load is about the same, or slightly less than, the unhitched value.

IMO, you should forget about having the TV "level".
Trucks are designed to have load added to the rear axle.
Because they have springs on the rear, rear-end squat when loaded is to be expected.
The front, OTOH, should not have load added. The front should not squat, but the rear will.
