Awesome. Makes a world of difference – Kyle
The flip down support jacks on my camper are inadequate, thin material and prone to bending sideways under load. These aluminum jack stands are the perfect solution - lightweight, easily stowable, infinitely adjustable, strong and very affordable. – Michael Blunt
I needed a couple of these for my camp trailer. They’re very sturdy and good quality – Tammara L.
Have used these many times, these strong suckers eliminate movement more than the preinstalled ones that were damaged due to backing over a hilly terrain. Easy to use, smooth functioning. – Shawn Storm
Works perfectly to secure our camper. Easy to store and utilize. Has provided significant stability and is highly recommended. – EM
