I wasn't sure that purchasing one of these tripod stabilizers was going to make a difference, but it does. I purchased this when i purchased the RV and set it up immediately and the trailer was extremely stable. A few weeks later, we on another trip, we got to the site a bit late and I decided to install the tripod stabilizer in the morning. Until then, i really didn't know how much of a difference the tripod made. That night the RV was significantly less stable. You could feel someone walking at the other end of the trailer. The next morning, i installed the tripod, and the movement was gone. Great product. Easy to use, small to store. My only complaint is that when jacking down the legs, it seems a bit flimsy, one leg want to put out past the others. Not a big deal though.
