Slide-outs are one of those RV conveniences we’d never willingly give up-until one of ours started to sag after a long stay at a windy, uneven boondocking site. That wobble underfoot made us nervous, so we set out to find a simple, reliable way to take the strain off the mechanism. Enter the Camco Eaz-Lift Adjustable Camper/RV Slide-Out Supports (2-pack, model 48870). Built from steel, each support claims a 5,000 lb capacity, fits up to a 5½-inch rail, and telescopes from 19 to 49 inches with incremental lock positions and a quick-release pin for fast adjustment.
We brought a pair along for several weekend stays and an extended dry-camp stint to see how they perform in real-world conditions-installation, fit, ease of adjustment, and whether they actually keep a slide-out level and prevent rail sag over time. Along the way we paid close attention to build quality, weight and portability (about 9 lb each), and whether the locking system lives up to its quick-release promise.
In this review we’ll walk through our hands-on impressions, the situations where these supports shined (and where they didn’t), and whether the Camco Eaz-Lift set is worth adding to your RV toolkit. If you’re tired of worrying about your slide-out every time you leave it extended for more than an afternoon, read on-we’ll share what we learned so you can decide if these are the “extra legs” your slide-out needs.
Our overview of the Camco Eaz Lift adjustable camper and RV slide out supports
We rely on these supports whenever we set up camp for more than a night - they stabilize the slide-out and take strain off the factory rails so our room stays level and free of sag.Built from durable steel, each unit is rated to hold 5,000 lb, and the pair gives us peace of mind during long stays or windy conditions. Adjusting height is straightforward: the supports extend from 19″ to 49″ with incremental locked positions and a quick-release pin for fast changes. In everyday use we appreciated how they fit standard rails up to 5½”, arrive as a ready 2-pack, and feel sturdy without being bulky.
On the practical side, setup is quick and the construction feels solid – the listed weight is approximately 9 lb which makes handling manageable for two people. Below is a short spec snapshot to help us compare at a glance:
- Protection: Keeps slide-out level and prevents rail sag/bending
- adjustment: Quick-release pin + incremental locks
- Fit: Works with up to 5½” slide-out rails
| Spec | Value |
|---|---|
| Height Range | 19″-49″ |
| load Rating | 5,000 lb each |
| Rail Fit | Up to 5½” |
What we found in the features from heavy duty capacity to the quick release pin and incremental lock positions
We were impressed by the raw stopping power and build quality – these supports are clearly designed to shoulder serious loads and keep our slide-outs stable over long stays. With a maximum rated load of 5,000 lb per support and a sturdy steel construction, they do exactly what we want: protect the slide-out mechanism, prevent rail sagging, and keep the room level while in use. The result is less stress on the frame and fewer cramps in our travel checklist. They also fit snugly on rails up to 5½ inches, and the two-piece set gives us balanced support on both sides.
- Heavy-duty capacity: 5,000 lb each
- Durable construction: Steel build for long-term use
- Rail compatibility: fits up to 5½-inch slide-out rails
- Includes: Two supports per pack
Adjustability is where these supports really shine for us: they extend from 19 to 49 inches with incremental locked positions so we can fine-tune height and eliminate any wobble. The quick-release pin makes raising or lowering fast and frustration-free – a simple pull and the height is set. Each unit weighs about 9 lb, so handling and storage are manageable, yet they feel solid under load. Below is a quick specs snapshot to help decide at a glance:
| feature | value |
|---|---|
| Capacity | 5,000 lb |
| Height Range | 19″-49″ |
| Rail fit | Up to 5½” |
| Pack | 2 supports |

Our detailed insights and practical recommendations for installation everyday use and long term care
When we set these supports up, the difference was immediate - the slide-out stayed level and the rails no longer showed any sag. For a smooth installation we recommend: place each support under the slide-out rail, use the quick-release pin to select the nearest incremental lock position, and extend until the support bears the load without forcing the mechanism. They adjust from 19″ to 49″ and fit rails up to 5½”,so measuring once before you raise the room saves time. Our everyday checklist includes:
- Confirm rail fit before lifting to avoid awkward angles.
- Use matched pairs – one on each side – to distribute load evenly.
- Start from collapsed height and extend gradually, listening for any binding.
- Set on firm ground or a small wooden pad so the base won’t sink.
These steps kept our slide-out level during extended stays and prevented rails from bending under long-term use.
For long-term care we treat them like any other steel support: keep the locking pin and tube clean, lubricate moving parts occasionally, and touch up any scratched paint to prevent rust. We also inspect them seasonally for signs of wear or bending - remember each unit is rated to hold up to 5,000 lb, so don’t rely on a single support for more than its share or use them on damaged rails. Below is a quick reference of key specs we found most useful:
| Feature | Value |
|---|---|
| Height | 19″-49″ |
| Max Load | 5,000 lb (each) |
| Rail Fit | Up to 5½” |
| Pack | 2 supports |

Pros & Cons
After spending time installing and using the Camco Eaz-Lift slide-out supports on our rig, we boiled our observations down to the essentials-what stood out as real strengths, and where we saw limitations. Think of these as the practical tradeoffs you’ll want to weigh before adding them to your camping kit.
Pros
- Serious load capacity: At 5,000 lb per support, these act like stout little stilts-more than enough for typical slide-outs and gives us confidence when parked for long stays.
- Wide adjustable range: 19″-49″ covers most situations we encountered, from low-profile slides to taller extensions.
- Incremental locks + quick‑release pin: The locking positions make fine adjustment easy, and the quick-release pin speeds up changes when we reposition or break camp.
- Durable steel construction: Feels solid and built to last; they don’t flex under load the way lighter supports can.
- Two‑pack convenience: comes with a matched pair so we could stabilize an entire side of our slide-out without hunting for a second unit.
- Protects the slide mechanism: When deployed, they noticeably reduce sag and keep the slide more level during extended use.
Cons
- Weight & transport: At roughly 9 lb each they’re not heavy, but they’re bulky-handling and storing two supports takes space and a bit of effort.
- Rail compatibility limit: Designed for up to 5½” rails; if your slide-out rail is larger you’ll need a different solution.
- Manual positioning can be fiddly: Getting the pin to drop into place on uneven ground or awkward angles sometimes required a second pair of hands.
- No dedicated footplate or case: ThereS no built-in wide footpad or storage bag included-on soft ground we used a block or board for better footing.
- Cosmetic wear possible: The steel construction is robust, but like any exposed metal gear it can show surface wear if left outside in harsh conditions-store them dry when possible.

Q&A
Q: What exactly do these Camco Eaz-Lift Slide-Out Supports do?
A: They stabilise and prop up your RV slide-out while it’s extended, helping keep the slide level and preventing rails from sagging or bending during long stays. We used them as a secondary support – not a replacement for the slide-out’s built-in mechanism - and they noticeably reduced rail flex when people were moving around inside.
Q: How strong are they?
A: Camco rates each support at 5,000 lb maximum. that’s the manufacturer spec, and in normal use we felt they offered robust backup support. Still, we treated the rating as a maximum per unit and followed safe practices: place supports on solid ground, don’t overload, and use more supports if you’re unsure of the load distribution.
Q: What heights do they cover?
A: They adjust from 19 inches collapsed to 49 inches extended, with incremental lock positions so you can fine-tune the height. The quick-release pin makes changing height simple – we could get both supports to the same height quickly.
Q: Will they fit my slide-out rail?
A: They’re designed to fit up to a 5½-inch slide-out rail. Before buying,we measured our rails and checked the rail profile. Most standard rails will work, but very wide or unusually shaped rails may not seat properly. If your rail has welded or odd-shaped edges, test fit or verify measurements first.
Q: How easy are they to install and adjust?
A: Very straightforward. Set the support under the rail, extend to the desired height, and secure the quick-release pin into the incremental hole. The pin makes micro-adjustments fast. We did find the first-time paint or finish can make the pin a bit stiff – a quick wipe of lubricant fixed that.
Q: Are they portable and easy to store?
A: Yes. Each support weighs roughly 9 lb, so the two-pack is easy for two people to handle and store in an RV compartment. They’re steel,so we recommend storing them inside and dry when possible to minimise surface rust.
Q: Can I use these on soft ground?
A: You can, but we advise putting a solid base under the foot - a wooden block or support pad – to prevent sinking.The metal foot is compact and will dig into soft soil; spreading the load keeps the support stable.
Q: Can I use these to lift a slide-out?
A: No. These are stabilisers, not jacks. They’re meant to support an already-extended slide-out and prevent sag.Don’t attempt to lift a slide-out with them as a primary lifting device – use the slide’s built-in mechanism or a purpose-built jack.
Q: How many supports should I use?
A: That depends on your slide-out. Most single-room slide-outs with two rails can be adequately supported with one support per rail (a two-pack). For very long or heavy slide-outs, or if you notice sag in the middle, consider adding additional supports at midpoint or using purpose-built central supports. We matched the number of supports to the size and condition of the rails during testing.Q: Any durability or maintenance concerns?
A: They’re made of durable steel and feel solid. To extend life,keep them dry when stored,periodically check and clean the quick-release pin area,and lubricate moving parts if they feel stiff. Touching up paint where chips occur will help prevent rust over time.
Q: Any fitment or usability quirks we ran into?
A: A couple of things: if your rail has paint transfer or grime, clean it so the support seats fully. The quick-release pin can be a little stubborn when new – a little lube helps. Also, very wide rails near the 5½-inch limit sometimes need a slight reposition to sit perfectly. We recommend test-fitting before relying on them for an extended stay.Q: Are there any safety tips we recommend?
A: yes – always chock wheels and stabilise the RV first, place supports on firm ground or a spreader block, don’t exceed manufacturer load ratings, and never use these as the sole safety backup if the slide-out mechanism is known to be damaged. Also check the supports periodically during extended stays.
Q: Do they represent good value?
A: For what they do – beefy steel construction, 5,000 lb rating each, wide height range, and a quick-release pin – we think they’re a solid value for RVers who spend time in one spot and want extra protection for their slide-out rails.They’re not a gadget – they’re a practical, mechanical safeguard.
Q: Any final tips from our hands-on use?
A: Measure your rails before buying, keep a small pad or block handy for soft ground, lubricate the pin if it’s stiff, and always pair supports with basic RV safety steps (chocks, levelers). When used properly, they gave us peace of mind and noticeably reduced rail flex during our tests.
