Camco 44560 RV Stabilizer Stack Jacks 6,000 lb, 4-Pack

Every trailer owner knows the feeling. You climb into the camper after a long drive, take one step toward the fridge, and the whole rig sways like it's floating. That rocking is what the Camco 44560 stack jacks are built to stop. It's a set of four aluminum stabilizer jacks that tuck under the corners of your parked motorhome, travel trailer, or camper and take the bounce out of everyday movement inside.

Here's the thing to understand up front. These are stabilizer jacks, not leveling jacks. They aren't meant to lift your trailer off its tires or carry the full weight of the rig. You get the trailer level first with your tongue jack and a set of leveling blocks under the wheels. Then you crank these down at the four corners until they're snug against the frame. That last part matters. Snug, not lifting. Once all four are firmly planted, the flex and sway that drives everybody crazy just settles down.

Setup is manual and honestly pretty quick once you've done it a couple times. Each jack cranks by hand to extend, and they reach up to 17 inches of height, so they'll bridge the gap between the frame and the ground on most sites. If you're parked higher off the ground than that, drop a block or two under the foot to make up the difference. A lot of owners speed the whole process up with a cordless drill and the right socket instead of cranking by hand, especially on a windy day when you just want to get set up and get inside.

The aluminum construction is a real advantage for gear that lives outside and gets wet. Steel jacks rust at the threads and eventually seize. Aluminum shrugs off the weather and stays light enough that swapping all four in and out of a storage bay isn't a workout. The set carries a 6,000 pound capacity rating, which is plenty of margin for the corner-support job these are doing. Remember, they're sharing the stabilizing load with the trailer's own suspension and tongue jack, so you're never asking one jack to hold the whole world.

Where do they earn their keep? Anywhere you park and actually live in the trailer. A weekend campsite, a friend's driveway, a seasonal spot at the lake. The four-corner setup is what makes the difference. Two jacks under the rear and two up front near the A-frame catch the sway in every direction, front to back and side to side. Walk to the bathroom at 2 AM without waking up the whole family. Cook breakfast without the coffee sliding across the counter. It's a small thing that changes how the whole trailer feels.

A couple of setup tips from experience. On soft ground, gravel, or fresh asphalt on a hot day, put a pad or a scrap of plywood under each foot so the jack doesn't sink or dent the surface. Give the threads a shot of grease now and then and they'll turn smooth for years. And don't over-crank. If you find yourself lifting a tire off the ground, you've gone too far. Back it off until it's just carrying the corner. Do that and this set will quietly do its job every time you park.

What they're not for: these won't level a trailer on a badly sloped site by themselves, and they aren't rated to hold a rig up for major undercarriage work. Use proper jack stands rated for lifting when you need to get under the trailer. But for their actual job, keeping a parked camper steady and quiet so the whole family sleeps better, a matched set of four is exactly what most trailers need.
