I know this has been discussed to nauseum, but I am currently towing my cargo trailer that is combined weight of about 7K LBS, and some stuff in the bed of the truck and of course fuel and two bodies. I have a slow leak in the air system which after a day of traveling, it squats the truck and puts more weight on the front of the tandem trailer wheels. The truck handles the squat fine with a dually, but it causes for concern. I just add air and go at this point. Timbrens won't do this and I will be dumping the air system depending on what I find, and switching back at some point. Hopefully its just a small hole in the air line.

Sumo springs work well for us , no air lines and ours are fully disengaged when there is no load in the truck also fairly easy install as well .

My air bag had a lot of excessive air, way too much in fact.
Enough to float 100 heavily laden trucks down the road.

But the problem went away after I divorced her....

Sounds like you need a weight distribution hitch.

What's the tongue weight on that trailer?

I wouldn't expect a 7k trailer to cause significant squat on a dually.

As someone else mentioned, a WDH might make sense if it's inducing that much squat.

Might also be how the load is spread in the bed.

IF OP is relying on air bags to hold the load, not springs per say, then yes, this will happen, not matter what is going on.

I barely pull of 200-300 lbs off the FA of my older now gone 3500's with 8500 lb RA's with a 1500 lb hitch load, from a 12K total trailer. A 7K with even 1000 lbs should not be pulling but 100-200 lbs off the FA, and not causing issues. I usually found it took at least 400, if not 500 or more lbs off the FA to cause steering issues with said 8 lug trucks.

X2 on Sumo's. They simply ride better than Timbrens. T's cause rebound. Sumo's dampen it.

And yes airbags are a PITA unless you have onboard air.

I've been really happy with the Timbrens on my truck. No messing with them and they give me a nice stable ride when loaded up with the fifth wheel and etc.

Lou, why in the HE!! do you need air bags on a modern DRW RAM with such a light load?

I am betting you are airing bags to put truck at unloaded ride height. Drop the air in your bags to 5psi and raise the ball to where the trailer sets level and carry on.

Your truck is designed to set level when placing a load on it and allow the overloads to start working.

This is NOT squat! My 11 DRW is riding level with 4,50# pin. NO air bags.

7k trailer with a DRW? 10% tongue weight I don't think so.

Have any of you guys actually read what truck he has and the actual weight of his trailer???

This is what you need Lou if your ball height is not adjustable.
