RAS with Firestone airbags

Anyone running both RAS and Firestone airbags? I have the RAS on my truck but doesn’t help with sag so decided I want the air bags now. I have a fastway e2 WDH and have dialed it in to where it still sags 1.75” in the rear and .25” in the front.

 

What are you pulling, unit, weight and tongue weight? You have RAS set up with the black disk? With that much sag with RAS, seems like the WDH is not set up correctly.

 

pulling a 33ft travel trailer with 820lbs of hitch weight and I messed with the WDH various times to get it dialed in but no matter what I do it still sags and it’s annoying

 

I used to have that set up in my 2007 Tundra RCSB. The RAS minimizes kick ups from the airbags. It has a damping effect kinda like shock absorbers. I still have to put the airbags my 2010 Crewmax 4x4. It has RAS installed.
