Simple install
Style: 5th Wheel Stabilizer Tripod Jack, Pattern Name: Stabilizer
Simple intsall, easily adjustable to diffrent hights, feet have a nice base so they don't sink, but can be placed on pads, helps with stability. Quality seems to be good. Nice weight not cheap and flimsy, durable enough to do the job, but not so heavy you need two people to move it.

Sturdy, Reliable, and Worth Every Penny!
Style: 5th Wheel Stabilizer Tripod Jack, Pattern Name: Stabilizer, Style: 5th Wheel Stabilizer Tripod Jack, Pattern Name: Stabilizer
This stabilizing tripod is very sturdy, well built, and performs exactly as expected. It arrived on time and in perfect condition. The difference it makes in 40+ kmh winds and 60 kmh gusts is remarkable, providing excellent stability and reducing movement significantly. I’m extremely satisfied with this purchase!
