Want to run my WD setup through you guys

[Elite130]

A few months ago, we traded in our Nissan Armada for a Titan. I went out today to setup my E2 weight distribution hitch today. I think I got it dialed in, but I need your opinion...

First, specs on the Titan: 2012 Nissan Titan (1/2 ton PU), Crew Cab, 5.6L, 4x4, premium utility package (aka tow package) 7200lb GVW, 9100lb trailer, 15,100GCVWR. I added a set of AirLift RideRite air bags.

Specs on trailer: 2011 Gulstream Amerilite 25BH, dry weight 4300lbs, GVR 7200lbs.

I have not weighed the setup yet, so I don't have any weight. I had both propane bottles mounted, battery and a full tank of water. I'm thinking I am about 300lbs short of fully loaded, but that weight will be evenly distributed through the trailer. Hopefully I'll be able to get weights on Friday. But here are the physical measurements I have. The measurements are from the top of the fender opening to the ground:

The starting line: Truck without trailer hooked up. 10lbs in air bags
Front 38"
Rear 39-1/8"

Trailer without WD Hitch 10lbs in air bags
Front 38-3/8"
Rear 37-1/4"

Trailer with WD Hitch and 10lb in air bags
Front 38-1/8"
Rear 38"

Trailer with WD Hitch and 30lbs in air bags
Front 38-1/4"
Rear 38-1/4"

Trailer with WD Hitch and 50lbs in air bags
38-1/8
38-7/8

From what I gathered today, I think I have the hitch adjusted correctly. The TT is level, the rise in the front was less than 1/4" and the rear is lower by 1/2" (thanks to the airbags). I am going to keep 50lbs of air in the air /bags. As the weight increases in the pickup, I will increase pressure to keep the same height ~38-1/2" to 39"

So what do you guys think? Am I on the right path? Do I have the hitch setup right?

Here are a couple pics of the final setup:





Thank you for your input!

Unless that trailer is real tongue heavy, I would venture to guess that the airbags are not really needed.
You are taking height measurements. Which is usually a good idea when trying to determining where the weight is going. However, with the airbags, you want to make sure that you are not taking too much weight off of the spring bars. They do provide good lateral stability which does help with the handling and towing manners.
In other words, the airbags may be undermining what the spring bars are trying to accomplish. I just don't think that trailer is heavy enough to warrant any real pressure in those bladders.

Just my opinion.
