I think you should try the Airlift 1000. I have them in my Ram and they do improve stability. I have found that 35lbs is better than 30lbs on my setup. Installation can be a problem but I found that once I had 95 percent of the bag in the coil (i.e. at least 50%of the bottom you can add a little air with a bike pump and the bag will slide right in - this assumes that you install the airlines before starting installation of the bags. Do not install without first attaching the airlines. Have pulled my TT over 10,000 miles the past 18 months with this setup.
