RVGUARD RV Stack Jacks 4 Pack with Storage Bag, Aluminum Stabilizer Jacks for RV Trailer Camper, Single Support Up to 6000 Lbs, Adjustable from 11" to 17"

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.

Sturdy. Easy to use, really easy. Using with a Casita travel trailer. Big improvement, no wobble in the trailer.

These work great to stabilize my little trailer. Stack upon themselves for easy storage.

I got tired of the various drive on blocks or drive on curves. My RV is ~9300#. I use a 6t air jack or a 12t hydraulic bottle jack and a bubble level. I lift the low spots up and place these in the appropriate areas and snug up these level jacks. I leave lifting jacks in place sharing the load with these. Seems pretty solid and no issues after leaving it sit for 2 weeks.

I bought these to level a 1800 pound pop up camper that I keep at a private campsite 3 seasons of the year. They were very easy to install and allow you to fine tune the pressure point.They make an amazing difference to remove any wobble while walking around inside the camper.

Haven’t used them yet but they seem like good quality.

GOOD PRODUCT QUICK DELIVERY WOULD USE AGAIN

I purchased in July 2024 for use on my pop up camper. She doesn't weight much around 1400 fully loaded, but I found these stabilizers to be a bit wobbly. They work as intended, but when raising the screw platform up, the jack stand can shift slightly which can angle the platform and may not lay flat. I will continue to use, but will be looking for something a bit more stable. Not a fan of the wobble while raising the bolt.
