Congratulations and welcome.
So far you've only dipped your toe into the whole suspension modification area! LOL Read around here, there are plenty of options and opinions about what is the best way to go (new sway bars, Sumo Springs, etc.). If you dig back far enough in the forum I've even posted a "how to drive your Axis/Vegas" thread:

I hope you get the suspension tuned to your satisfaction and have many years of happy RV'ing.
