RVMATE Stack Jack 4 Pack, for RV, Camper and Trailer Stabilization, Aluminum RV stabilizer, Adjustable from 11 inch to 17 inch

Easy to use, strong

They’re exactly what we ordered

Easier than factory mounted stabilizers. Not jackstands they just stabilize the trailer from rocking. Works great

Impressed! These made the perfect adjustable supports for the 24' floor support beam I recently installed under my house. The trick is to use a hydraulic jack to do the lifting and the support screws for fine tuning. So far they handle the weight just fine & I have no doubt they'll be under there for a long time to come!

We use these on an older model camper and they work great

I purchased these as I needed one for truck camping and planned on using them on my trailers later. When on the road I may sleep for 3 hours before I am back behind the wheel. This works great as my wife sleeps in the back seat comfortably. I have a short bed crew cab truck with a bed 5" shorter than me. As I am a side sleeper the length is no problem until I get leg cramps. Then the truck looks like it is traveling over Missouri's back dirt roads where you can scramble eggs or make milk shakes without a whisk or blender. A few words from my wife after one sleep stop where neither of us slept and I bought these to correct the leg cramp rock and roll. One jack under the hitch receiver raising the receiver about an inch and all I heard from the back seat was restful slumber. I noticed I slept better as well as the wind did not rock the truck. I carry all 4 in the truck should I need to support both sides of the rear and the front should the winds be extra fierce in Oklahoma and Texas.

They are working fine. I bought as extra support for my fifth wheeler take some of the pressure off the built in jacks. The land is soft and very uneven.

Light weight, kind of flimsy. Good for the price. 4/5 stars.

The product is nice and value for money
