Bilstein1.75 with rear air bags

Hey TW, this is my first post. I have a 07 DCLB TRD Sport 2wd and I'm putting Billy's on all four, with the front at 1.75. I tow a 5000# trailer on occasion and was planning on a Wheelers 1.5 AAL. I don't have the rear TSB, and don't want to be nose high. Can I install Firestone ride right 2047 air bags instead of the AAL, to level the ride, or would I need both the AAL and air bags?Also, are the standard rear 5100's recommend with this set up?

Any help would be greatly appreciated.
Thanks

 

I can only speak from experience with 4wd DCSB, but AirLift airbags and 5100's set at zero have been a winning combination.
How is your rear leaf without the trailer?
You have spring or is it toast?
The AAL is not going to compensate for dead leafs, especially with a trailer.
My airbags are nice because you can air down when you want and obviously, air up for a load.
I do not think pre-loading the front, especially just for looks, is a good idea.
It decreases the spring's effectiveness.
