I use them and they do make a noticeable difference in tt movement when walking around in the trailer. We have a 33 ft Rockwood tt with 2 driver side slides. I just snug them up. I make sure I don't over tighten them. I also check them daily, just as I do the corner stabilizers. I don't think if 1 tire goes flat I'll see a problem due to the fact that I still have 1 good tire and 2 corner jacks that should support that side of the tt. What if both tires go flat, or any number of other problems arise? The chance is pretty slim. Do I need them? No. Do I like them? Yes. Haven't had a problem yet. It would be great if you could borrow a set some time and make your own judgment on it. I also have a friend that uses them. He also likes them. Good luck with your decision.
