When an RV and trailer repair shop outside Sioux City called us about a rotary two post lift, the owner wasn’t shopping for the cheapest lift he could find — he was shopping for the one that would still be square, quiet, and passing its own inspections a year from now. His shop runs a steady stream of travel trailers, fifth wheels, and towable rigs through annual state inspections, and a lift that fights him on lock engagement or drifts out of level costs him appointment slots he can’t get back. We walked him through a Rotary two post lift built for exactly that kind of duty cycle, and we’ve stayed involved with that lift from the day the truck backed up to his bay through its first scheduled service call.

Why an RV and Trailer Shop Chose a Rotary Two Post Lift
Most RV and trailer shops default to a four-post drive-on because towables are long and awkward to spot. This shop went a different direction. Their bay traffic is mixed — tow vehicles, service trucks, and the occasional light trailer axle job — and they wanted a lift that could handle a pickup one hour and a trailer frame the next without repositioning ramps. A rotary two post lift with the right arm configuration and reach gave them that flexibility, plus a smaller footprint than a four-post runway setup would have eaten in their existing bay.
We also talked through the brand question directly, because it comes up on almost every call. Rotary has been building two post lifts for decades, and the parts pipeline behind that history is a big part of why we point RV and trailer shops toward it. When a cylinder, a rear post, or a lock assembly needs replacing five or ten years down the road, Rotary’s distribution network means we can usually get a firm lead time within a few days, even on parts that aren’t sitting on our shelf. For a shop that can’t afford a bay sitting dark for weeks, that pipeline matters as much as the lift itself.
Getting Ready for Install: Concrete, Clearance, and Delivery
Before we ever load a lift on the truck, we ask the same questions every time: is there a pit, what’s the concrete thickness and age, and does the shop have a forklift on site to help unload. For this Sioux City shop, the answers determined a lot of the schedule. Their slab was original to the building and needed a core sample before we’d commit to anchor specs, and because they don’t run a forklift, we coordinated a liftgate delivery and planned the unload window around their open bay time.
Freight and lead time on a rotary two post lift can run anywhere from a couple weeks to a couple months depending on the model and options, so we always build the install date around realistic delivery windows rather than promising a date we can’t hit. We also walk through overhead clearance early, since RV and trailer shops sometimes have taller doors and higher ceilings than a standard automotive bay, which can open up options on column height and arm reach that a tighter shop wouldn’t have. Getting that conversation right before the truck ships saves a rescheduled install every time.
Install Day and the First Alignment Check
On install day, our crew set anchors, squared the columns, and ran the lift through a full cycle test before handing it back to the shop. With a rotary two post lift, getting the columns plumb and the cross-brace torqued correctly up front is what keeps the arms swinging free and the carriages tracking evenly for years — cut corners here and you’re chasing a binding lock or a leaning column within months. We checked cable tension, verified the safety locks engaged evenly on both sides, and ran a load test with a service truck before we called it done.
We also spent time with the shop’s techs on load points specific to trailers and towables, since frame contact points on a fifth wheel or travel trailer axle don’t always match a standard vehicle lift chart. Getting arm placement right for those loads on day one meant fewer awkward re-spots once inspection season hit. That kind of walk-through is standard for us on any commercial install, but it’s especially worth the extra twenty minutes for a shop running mixed RV and trailer work through the same bay.
Annual State Inspections: Where the Lift Earns Its Keep
State inspection season is where this rotary two post lift really goes to work. Trailer and RV inspections mean a lot of underside time — brake lines, axle components, frame condition — and the shop needed a lift that would hold a unit rock steady at working height for extended periods, not just a quick in-and-out oil change stop. The arm restraint system and lock engagement on this Rotary model gave their techs confidence to work underneath without babysitting the lift every few minutes.
The shop also runs a tighter schedule during inspection months, which meant less tolerance for downtime. We built their maintenance routine around that reality: cable inspection, hydraulic fluid checks, and lock mechanism lubrication on a schedule that lines up with their slower months rather than waiting for something to fail during peak inspection traffic. A rotary two post lift that’s maintained on that kind of rhythm rarely surprises anyone, which is exactly the point when a whole season of inspection revenue depends on the bay staying open.
The First Real Service Call: A Seal, Not a Failure
About a year in, the shop called us about a slow drip near one of the cylinders — the kind of thing that alarms an owner the first time they see it but is a routine wear item on any hydraulic lift. We’ve seen this exact scenario play out with other Rotary lift owners: a seal reaches the end of its service life, fluid shows up on the floor, and the fix is a reseal or cylinder rebuild rather than a full replacement. Because Rotary parts move through an established distribution chain, we had the seal kit and cylinder components sourced and on hand well within the week, and the repair didn’t cost the shop more than a partial day of downtime.
That first service call is often the real test of whether a lift purchase was the right call, and it’s also where the brand history behind a rotary two post lift pays off in a way that’s easy to overlook when you’re just comparing sticker prices. A lift brand with decades of parts continuity means the cylinder, the lock casting, or the cable on a machine installed five or ten years ago is still identifiable and orderable, not a mystery part number nobody stocks anymore. That’s the difference between a half-day repair and a lift sitting idle for a month waiting on a part that has to be reverse-engineered.
Cylinder and Cable Wear Specific to Trailer and RV Work
RV and trailer shops put a different kind of stress on a two post lift than a typical passenger car bay does. Longer hold times at working height, heavier concentrated loads on fewer contact points, and frequent full-range cycles as techs reposition units all add up to faster wear on cylinders, cables, and locks than a shop doing quick oil changes would see. We flag this for every RV and trailer customer running a rotary two post lift, because the maintenance interval that works fine for a general repair shop often needs to be tightened for this kind of duty cycle.
For this Sioux City shop, that meant moving cable inspection and cylinder seal checks to a shorter rotation than we’d typically recommend, plus keeping a rebuild kit on hand rather than ordering reactively. We also talked through the option of carrying a spare seal kit in their own parts bin, since a shop running inspections on a deadline can’t always wait even a short lead time for a part to ship. Small adjustments like that, built around how the shop actually uses the lift day to day, are usually the difference between a lift that runs trouble-free for a decade and one that nickel-and-dimes an owner with surprise downtime.
What We’d Tell Any Shop Considering One
If you’re running an RV or trailer shop and weighing a rotary two post lift against other options, the honest advice is to think past the install and into year three, five, and ten. Ask about parts availability before you ask about price, because a lift that’s cheap up front but orphaned on parts in a few years will cost you far more in downtime than you saved at purchase. Ask about lead times on cylinders and locks specifically, since those are the parts most likely to need attention on a lift running heavy inspection-season hours.
We’d also tell any shop to be upfront with us about concrete condition, forklift access, and overhead clearance before we quote a date, because those details drive the real install timeline more than anything else. A rotary two post lift is a long-term piece of shop equipment, and the shops that get the most out of one are the ones that treat the first year — install, first inspection season, first service call — as the foundation for everything after it, not just a box to check off the to-do list.
