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

I thought them bigger. however, they do help stabilize my RV. Hardly felt the wind.

They work well for me so far and they look a lot better.

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.

Easy to install & kept our trailer stable.

Always had a bounce in our travel trailer. Then I thought about these stands. Put them under the tandems and no more bounce. Nice heavy duty construction. Light weight yet strong. Very happy.

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!

Pretty light duty but will work for small campers

We like these because it helps stabilize camper and you don't feel as much movement
