When removing the rear twin wheels, drill eight 3/8" holes in the hardened chassis frame and trim the RV studs, avoiding kinks and electrical cord easier than this. It's an easy setup. I already have a rear tracBar installed for stability. Those sumo springs probably help with stability as well. My goal was a smoother ride. There's always a rumble and rattle in an RV when you're dragging your home down the freeway. This setup reduced the shaking significantly!
