Houston, we have a problem!! Not sure how to fix.
Ok, so went to the CAT scales, man was that an experience.
Here are my numbers:
TV+TT+WDH = Steer 3500, drive 4300, trailer 6460, total 14,260
TV+TT-WDH = Steer 3260, drive 4660, trailer 6340, total 14,260
TV = Steer 3700, drive 3180, total 6880
By my calculations this makes my tongue weight 1040 which is 13% of the loaded trailer weight of 7380.
I drive a 2011 F150 SuperCrew, 6.5 ft bed, EcoBoost with 3.55 axle. The ratings are Steer 3900, Drive 4050, GVWR 7350, GCWR 15,500 (found on Ford site), towing capacity 9600, payload 1431. I had a simulated load for each child and my wife, in their seats, as well as my dog. Put a simulated load of clothes in trailer where we usually put them. All items in storage where they have always been. Tires at 44 psi.
Equalizer E4 14,000 lb hitch with 12,000 lb ball and arms. (don't ask, dealer mistake)
My travel trailer is a 2015 Jay Flight 28 BHBE. GVWR 9250, weight from factory 6710, tongue weight from factory 610 (from Jayco site). Tires at 65 psi.
Why would my drive axle weight be so high when hitched up? Do I need to adjust my hitch to put shift more weight? Any thoughts greatly appreciated.

Is that 44lb figure the pressure in the truck tires?

Based on your TV's front axle weights, you can still transfer another 200lbs off the rear axle (3,700lbs - 3,500lbs). It's to be expected that the drive axle weights will increase even with a properly adjusted WDH..., the main job of the WDH is to return the weight to the front axle that was removed do to the weight placed on the TV's hitch ball.
The WDH will also transfer some weight off the TV's rear axle to the TT's axle, 120lbs in your case (6,460lbs - 6,340lbs).
If your TV's GVWR is in fact 7,350lbs, your CAT scale results state you are over by 450lbs ((3,500lbs + 4,300lbs) - 7,350lbs)). Don't forget, the tongue weight is supported by the TV.
Your correct on the 13% tongue weight (1,040lbs), and 13% to 15% is where one should be on the 28 BHBE.
Great effort at the CAT scale

The 44 psi is the tire pressure, that is to get the max weight rating of the tire.
I realize I'm 450 over the GVWR, that is the dilemma. To readjust the hitch and weigh again or trade my truck?

Simple answer is yes you should adjust the hitch to return more weight to front axle. I don't have an Equl-i-Zer so I can't tell you how to do this, but on my hitch its a matter of lifting the torsion bars a bit higher.
The other thing that jumps out at me is these weights confirm that you are exceeding the F150 GVWR by ~450 lbs. Personally I wouldn't be to concerned about this, but that is something I think you need to be aware of.
Of course if your simulated loads were over simulated, then its possible that you really aren't that far over. You could try to redistribute the load in your TT to reduce the tongue weight, but I would be very cautious about this since you are already at the suggested 13% mark. To much less and you could introduce a tendancy for sway.
Great work on the weights. Know that you know what you are dealing with its much easier to make adjustments.

I own an Equalizer hitch and from what I have read, you need to adjust the angle of the hitch forward and that will shift the weight around. You can also go to http://www.equalizerhitch.com/Equal-...structions.php and download the adjustment instructions. I know from looking at my hitch my hitch is tilted to the back of the truck.

That is what I read in my manual. More washers or elevate the L-bracket on the TT tongue. I emailed Equalizer and they stated to add the washers as you want to keep the sway bars parallel with the frame. But, this doesn't really fix my overall problem of too much weight for GVWR and GAWR. I'll still be over with growing kids and more toys to come. So, I'm looking to upgrade and have only 1 more trip planned, very short distance, <5 miles, that I'm very comfortable with.
