Thought I'd only need them on rough terrain or slopes. Bought and not used for a while. But I saw a video on YouTube where someone mentioned that it reduces the RV's wobble when moving inside. So I used it on our recent trip and it made a huge difference! This will prevent the tires from moving back and forth slightly when you step inside. This made the whole camper feel much stronger. And the security of these pads is unbeatable.
