OMG I'm hauling a rocket launcher

2011 Ecoboost with Reese dual cam sway control.
Hauling 2012, Salem 27RKSS

I was hauling pretty much level before I installed the firestone air shock system but now I am towing what looks like a scud missile platform.

Worried about the back 2 stabilizer jacks getting pinched on the road.
Truck with 10 lbs air in the Air bags sits as follows.

Front end = 36 3/4 inches from ground to top of wheel well opening
Rear end = 40 inches from ground to top of wheel well opening

The trailer set up level on pavement is approximately 22 inches from where the pavement is to the top of the coupler inside where the ball would sit inside.

I can't lower the ball any more and if I invert the bar it takes it higher.

Any suggestions?

E-trailer site states that the truck should be within an inch difference between front and back at the wheel wells.

Are you sure the mounts on the trailer are the correct orientation for your coupler type?

If the trailers coupler is on the bottom of the frame, the brackets are installed differently on the Equi-li-zer hitch. Perhaps it is the same for the Reese.

You could also have too much torque on the chain/bar.

A photo of the connected trailer combination might help.

I just realized you had the problem when the airbags were installed.
(Just got up - coffee soaking in sorry).

Why did you choose 10 PSI of air?
Is that the minimum inflation?
The bags should not lift the truck at all when there is no load.

You may have to redo your hitch's geometry for the new truck suspension mod.

This was it before the air system installed.
The front end was actually higher than the back.

Looks like the trailer was riding too high before you put the bags in the truck.
Your truck also looks like it is riding low (like it is a tad overloaded or the hitch was not correct).

Even without the airbags you needed to lower the coupler by lowering the ball; with the airbags the adjustment of the ball upwards will most likely be more.

I'm not sure but something isn't right.
I have to add 15 lbs unloaded for the bags to even move the truck.

Does your truck sit normal unloaded ?

Pics ?

The rear of the truck is lower then the front, but the trailer seems to be higher in the front them the rear? Was that a level parking lot or was there some slop to it? The trailer as a whole seems to have a pretty high ground clearance. By looking at this picture if air shocks were added and "aired up" I could see why the nose of the trailer would be pointing up. Seems like your receiver ball needs to be lowered..

I was hauling at 40 lbs to take out the "6 months in a leaky boat" syndrome.
Min. is 5 lbs
Droppig from 40 to 10 settled the rear end height down some but not much.
Even unloaded the truck always sat higher in the back without the air bags installed.
Any suggestions for links to a good video inatall with air bag support?

If the truck and trailer were level and handling well, why install an air shock system ??

I am not familiar with air shocks, but can you run less pressure ??

By putting pressure in those puppies, you now have significant more stress on the shock mounts instead of the springs. Shock mounts are fabricated to take the normal up and down stresses of the shocks, but I wonder about long term problems with carrying the weight of the truck.

E-trailer site states that the truck should be within an inch difference between front and back at the wheel wells.
All wheel wells are not equal front to back. It depends on the vehicle, and whatever the designers deemed the best look. The frame of your truck riding level might not result in the top of the fender wells being the same measurement to the ground. But I don't want to crawl under my truck doing setup measurements, as probably most people don't want to, so the WDH manufacturers use the fenders as references.

My suggestion would be to run the least amount of air pressure in the shocks that the manufacture recommends, and get your truck axles and trailer axles weighed with both the spring bars in place and then removed and then the truck alone......all with no changes in passenger or cargo placement. Ideally, the trailer should be camper ready, with normal passenger and cargo load in the truck. Bring your results back here and let's see what you got.

the pic of the receiver and ball was taken last night after I flipped the bar. I figured that the ball would need to be dropped and the only way to do that was to flip the bar and reinstall the ball at a lower point.
That way, once the weight of the trailer is applied the truck rear end drops.
Weight displacement chains are applied at the point where the tougue weight is on the ball but not totally supported by the truck reciever alone - correct?
Then I can drop all the weight of the trailer onto the truck and adjust the air system to level the front of the TV to the rear - Correct?
