Camco Eaz-Lift RV Slide-Out Stabilizer Support, Set of 2

When your slide-out rolls out, all that weight, the couch, the slide floor, the cabinets, sometimes a whole kitchen, hangs off the rails. Every time somebody walks across the room it can bounce and flex. These Eaz-Lift supports take that load off the slide mechanism and put it on the ground where it belongs. You set one under each end of the room, snug them up, and the floor stops moving. Simple as that.

That movement isn't just annoying. A slide-out that bounces every time you step into the room is putting steady stress on the rails, the rollers, and the seals that keep water out. Over a long weekend it's a minor irritation. Over a season of full-time living or a summer parked at the same site, that constant flex is the kind of thing that wears a slide out early. Supporting the room from underneath is the cheapest insurance you can put under an RV.

Each support adjusts from 19 inches all the way up to 47 inches, so they reach from a low travel trailer skirt to a tall fifth wheel with room to spare. The main body drops into incremental locked positions that carry the load, then a fine adjustment gives you another 14 inches of travel so you can dial in firm contact without over-cranking. Here's how that works in practice. You extend the body until the pin drops into the closest locked hole below the slide, then you turn the fine thread up until the top just kisses the underside of the room. That last bit is what actually snugs it. Get it hand-tight and you'll feel the bounce disappear.

They're rated to hold up to 5,000 pounds each, which is well past what most slide rooms actually weigh. That means real margin whether you're steadying a small dinette slide or a big living-room slide loaded with furniture, a slide-out fridge, and everybody standing in it at once. The top is a universal design that sits under any slide-out rail, so you don't have to match them to a specific brand of camper or slide system. If your rig has a slide, these fit under it.

A couple of tips from the field. On soft ground, gravel, grass, or a muddy site, set each support on a pad or a scrap 2x4 so the foot doesn't sink and lose your setting overnight. On an uneven pad you may need to shim the foot flat before you crank up, otherwise the height can bind as you turn it. And remember these are supports, not jacks. You're taking the flex out of the slide, not lifting the whole room off its rails, so snug them by hand and stop there. Back them off before you retract the slide, every time, so nothing is fighting the motor when the room comes in.

The steel is treated to resist rust, but like anything that lives under an RV, they'll last longest if you knock the mud off and let them dry before they go back in the storage bay. If you camp near salt water or on the coast, give them a rinse now and then and they'll stay clean. Each one has a space-saving handle so it collapses down small, and the pin that sets the height is tethered so it stays with the support instead of disappearing into the campsite gravel. Keep the pin seated when you store them and it won't tangle on you.

You get a set of two, which is what a single slide-out usually needs, one at each end. A wider room or a rig with multiple slides may want a second set so every slide gets a pair. The packaging is labeled in English and French. These are built for RVs, travel trailers, and fifth wheels, so if you're steadying a camper slide, this is the right part.
