RVGUARD RV Stack Jacks 4 Pack, 6000 Lbs Aluminum Stabilizer Jacks

We have a 24 foot camper trailer that we use several times a year. One of the only things That bothers me is the camper rocks or moves when someone walks around. Its not a high-end camper and the adjustable stability supports aren't the best. I ordered the supports and I am writing this review in our camper in bed. Part of the reason our camper tends to rock is that the wheels are on suspension springs and no matter how secure the corner supports are, the camper will still bounce and move on those springs. I engaged the equipped corner supports and used the 4 I am reviewing on both sides of the wheels. 2 on each side. The camper frame runs the length of the camper on both sides. This has greatly improved the amount of movement of the camper. These supports are light but strong and stable. They are very easy to adjust and easy to tighten simple but very effective design. Everything is included and easy to set up. They are a little short for reaching the camper frame but small sections of 2x4 easily solved the issue. Pleasantly surprised that these supports work so well at a very reasonable price.

I was doing a kitchen repair that required removing and reinstalling a large kitchen wall cabinet above the counter top. I bought a four pack of these and they saved my day. These camper jacks made easy work of supporting the cabinet while I unscrewed and lowered it from the wall. Then when it was time to hang the cabinet again the threaded lifting post made easy work of precisely lifting the cabinet to the proper elevation for leveling and installation. They fit perfectly between the kitchen counter and cabinet bottom with 2x4 blocking. They are rated for 6000 pounds per 4 jacks, or 1500 pounds each. I have not tried lifting that much weight, but I would not even attempt it. I think they are more suitable for lighter loads not exceeding 500 pounds on each jack stand. The frames are made of cast aluminum. They are light weight, burr free, look very nice and will not rust. The screw posts are zinc plated steel threads that engage the stand by a M20 x 2.5 millimeter steel hex nut. The hex nut slip fits into a female hex socket on the stand to prevent rotation. There is about six inches of travel provided by the threaded lifting post. The distance across the hex nut is 1.1" or about 28mm. The design is very simple and I would definitely buy these again. They are sold and described as a RV STABILIZER jack. I think they will work well as stabilizers, but they will need to be on a good solid concrete base and evenly loaded in order to perform well.

We actually used these jacks to level and lower a new deck. Held great and lowered it evenly and easily. Worked like a charm.

Great jacks, they look a little weak but they are not. They do the job they were created for.

Great product for the price. Easy to use. Quick shipping. Packs well. Makes the camper completely sturdy.

Worked as they should Good quality , no issues

Sadly they started bending with too much weight

Nice jacks for stability on the fifth wheel. Rubber cap is a nice touch.

Good quality, but there are no rubber included

Ordered in March to level my trailer. Finally opened the trailer up this weekend and while it has the four bases, it only came with 2 screw jacks. Very annoying, and worse yet I missed the return date by a week. Absolute waste of money.
