This is my third caravan. I had no problems with the previous two, they wobbled back and forth. So I didn't know this was the cause until the trailer slid forward about 6 inches and bent all 4 stabilizer bars (one beyond repair). Being in the trailer when it happened scared the shit out of me. I came across your product, read the reviews (mostly positive), so I ordered a set. They are EXACTLY as advertised! Installation took only MINUTES and stopped 100% swaying! I would (and will) recommend the EPOARTIST Camper Wheel Chock Stabilizer to absolutely everyone!
