I like their concept but after using them on my 33ft split trailer I'm not sure if they really helped stabilize the trailer. I feel like it has more to do with the split axle design because I've experienced the difference regular cross pads make on standard axle trailers. I've tried tightening them many times and only tried a little; same result. I want them to work better. They're good quality and pretty easy to use, just not as efficient as I was hoping.
