When an RV and trailer service shop on the edge of the Des Moines metro started typing “2 post car lifts near me” into Google, they weren’t just shopping for equipment — they were trying to figure out if a two-post lift could even handle the mix of tow-behind trailers, cargo vans, and the occasional pickup that came through their bay. A year later, that lift is the busiest piece of equipment in the shop, and most of what made it work happened before it ever arrived. We’re Auto Lift Services, based in Ames, and we’ve installed enough of these in shops just like theirs to know the site survey matters as much as the lift itself.

Why an RV Shop Even Considers a Two-Post
Most people searching “2 post car lifts near me” picture a sedan shop, but plenty of RV and trailer outfits end up on the same page. This particular shop was doing wheel bearing service on travel trailers and small RVs using floor jacks and stands, and it was eating hours out of every job. Bearing packing and hub inspection need the wheel hanging free and the tech at a comfortable working height — exactly what a two-post arm lift is built for, as long as the frame contact points line up.
The catch with trailers and RVs is frame geometry. Not every chassis has clean, factory-rated lift points like a car does, so before we quoted anything we asked for photos of the frame rail spacing and axle setup on their most common units. A Rotary two-post with adjustable arms and enough reach handled almost everything they ran, but we flagged a couple of longer travel trailers that would need cribbing or a four-post drive-on instead. That’s the kind of thing you want to know before the lift is bolted down, not after.
The Site Survey: What We Actually Check
Before we ever talk lift models, we walk the bay. Ceiling height matters — a two-post needs enough clearance for the vehicle plus the lift’s max rise, and RV shop bays with mezzanine storage or ductwork sometimes surprise people. We also check for a forklift on site or unloading equipment, because a two-post arrives on a flatbed as a set of heavy steel columns, and getting it off the truck without one adds real time and cost.
Concrete is the other half of the survey. Two-post lifts anchor into the slab, and that slab needs to meet a minimum thickness and cure age or the anchors won’t hold rated capacity — full stop. This shop’s bay was a newer pour, four inches, well within spec, but we’ve walked into older buildings with patched or thin concrete where the answer was “core drill test first.” We also look at whether there’s a pit nearby, drainage, and where the power drop for the hydraulic unit needs to land relative to the columns. Getting all of this on paper during the survey is what keeps install day from turning into a change-order fight.
Choosing Between Symmetric and Asymmetric
For this shop, we landed on an asymmetric two-post because most of what rolls through their bay still has a driver’s door that needs to swing open once it’s in the air — techs getting in and out to check hub torque and bearing preload. A symmetric layout would have worked fine for straight bearing pulls, but asymmetric arms swing the vehicle slightly off-center from the columns, which gives more clearance and balances weight the way most frames actually sit.
We talked through drive-on versus arm-style too, since some RV work is easier on a four-post platform. In the end the two-post won because their bay saw more variety day to day, and arm lifts adapt to different frame widths and wheelbases better than a fixed-rail platform does. Capacity was the last piece — we spec’d above their heaviest common unit with margin, because loading a two-post at its stated max every single day shortens cable and arm life fast. That’s a lesson we’ve learned the hard way on other jobs where the lift was undersized from day one.
Install Day: Anchors, Power, and Alignment
Install day for a two-post is mechanical work, not magic. Columns get set plumb and squared to each other first — get that wrong and the carriage will bind going up. Anchors go into the slab at the depth and torque spec called out by the manufacturer, and we don’t shortcut that step even when a customer is anxious to get back to work. The hydraulic power unit gets mounted, lines run, and the equalizer cable gets tensioned and checked before the lift ever takes a full load.
We ran this shop’s first cycles empty, watching both columns rise together, listening for anything uneven in the hydraulics. Then we loaded a trailer axle assembly onto the arms as a real-world test before signing off. This is also when we walk the crew through daily inspection points — cable wear, arm pin engagement, locking mechanism — because a lift that’s installed right still needs to be checked right, every day it’s used.
First Service: Wheel Bearing Work on the New Lift
The first real job on the new two-post was a set of trailer hubs with worn bearings. With the trailer lifted to a comfortable working height and both wheels hanging free, the tech pulled hubs, cleaned races, repacked, and reset preload in a fraction of the time it took on jack stands. No crawling, no working at ground level with a light in one hand. That single job convinced the shop owner the lift paid for the install cost in labor time alone within a few months.
What surprised them more was how it changed inspection habits. With vehicles up in the air quickly and safely, techs started catching worn seals, loose U-bolts, and cracked leaf springs they’d have missed doing bearing work at floor level. A two-post isn’t just faster — it changes what a tech actually sees during routine service, and that shows up in fewer comebacks.
What Goes Wrong When Shops Skip the Survey
We’ve seen shops order a two-post online, get it delivered, and then discover the slab won’t hold anchors, or the ceiling height is six inches short of full rise. At that point the options are expensive: core drilling and re-pouring a pad, or returning a lift that’s already been freighted in. Every one of these problems shows up in a proper site survey done before the order, not after.
The other common miss is power. Two-post lifts need a dedicated circuit sized for the hydraulic power unit, and older buildings — especially converted garages or repurposed RV storage buildings, which is exactly what a lot of trailer shops start out in — sometimes don’t have it. We check electrical capacity as part of the same visit, because rewiring a bay after the lift shows up adds days to a job that should take one.
What This Shop Would Tell Other Iowa Owners
A year in, this shop’s advice to anyone else typing “2 post car lifts near me” into their phone is simple: get someone out to look at your bay before you pick a model. Frame geometry, ceiling height, slab condition, and power all decide which lift actually fits, and none of that shows up in a spec sheet or a photo. They also said don’t undersize on capacity just to save money up front — the margin matters once real work starts piling on the arms every day.
We’ve run this same conversation with shops from Des Moines to Waterloo to the Quad Cities, and the pattern holds. A two-post lift is straightforward equipment, but a rushed install without a real site survey turns straightforward into expensive. Do the survey first, buy the right capacity, and the lift will outwork almost anything else in the bay for a long time.
