Review on Camco Heavy Duty Leveling Blocks (4 Pack) - 🟨 Ideal for Leveling Wheels, Jacks, and Axles - Yellow, Model 44501 by John Lewis

. So I have these trailer jacks that fold under my trailer just need an extra inch or so and that's where they come in, they do a good job for their purpose. They're just cheap plastic, but they don't seem to break. My trailer weighs about 800 pounds max. I have an interurban trailer that I towed behind my Subaru Outback, they work for what they were designed for. They are stacked together in a beautiful bag that comes with the set. I have small pieces that go into the block to smooth it out and they work fine. If you needed more, clicking them together I could see how they would work very well. But for what I'm looking for, they work great
