I installed the Sumo Springs on my 2018 Thor Siesta three months ago. Easy install. I used the coach hydraulic levelers and a bottle jack for safety to remove the factory bumper stops. Took off on a 5 week road trip across 13 states and they made a huge difference. Reduced side sway and the dragging going out of simple driveways. They were very easy to install. Took about an hour total time. A reasonable modification (around $300).
