Air bags or R.A.S

Has anyone used the R.A.S (Roadmaster active suspension)
Air bags or the ras I'm trying to decide on one or the other. I do like the added suspension of the ras if they work as advertised.

I can't speak for the R.A.S. but i have had airbags on my last few trucks and love them. You can take the "squat" right out. I typically run 30psi when I pull the travel trailer. They are reasonably priced and easy to install

I watched all the videos and animations on the RAS but I'm not sold. What I really don't like is the rear mount and how it JUST clips on. It seems to me that there is a chance that it could pop off. I'm not advocating the airbags because I have them but I like the fact that I can adjust the height depending on the load. IMHO there is no better ride than on air.

I had the firestone ride right air bags on my last truck and really liked them. Easy installation and they performed good. Now that we are looking at a new fiver I have ordered another set for this truck because of the increased weight. On our last trip, driving at night, some of the oncoming traffic thought I had my brights on, so with the heavier pin weight I want them just to level the truck out.

I have bags on my suburban and they do what I ask of them which is to level it .
I think onboard compressors or controllers are a waste of money for as much as I need to adjust them I cant see justifying the price .
you cant increase towing capacity but you can enhance it !

I use PacBrake Air Bags. You don't need an onboard compressor, you can just air up individual bags and deflate to the pressure you like. You can just carry a small 12 volt air compressor.
Never enough camping!!

Also can't speak for the RAS, but I really like the Firestone bags. I have run them at 30-40 psi towing, and let the pressure off to 10psi otherwise. At that low pressure, the ride is just a little firmer than the stock suspension.

I went with RAS. For me it was cheaper, easier to install, and there is no more work after it is installed. Just hitch up and go. No trying to tweak air pressure, no worries about deterioration over the years. RAS helped my rear end sag, improved body roll loaded and unloaded, and eliminated axle wrap. Not sure about other vehicles, but RAS does wonders for the soft suspension of the Excursion.

We always run bags on our trucks towing all over the place. Air Lift has a $100 rebate going on right now. $50 for the bags and $50 for the compressor kit.
