Twelve months ago, an RV and trailer service shop in east-central Iowa had a problem a lot of shops in that niche run into: their existing lift equipment simply wasn’t rated or shaped for the wheelbases and weights that show up on a fifth-wheel or a dual-axle utility trailer. They came to us looking for vehicle service lifts & jacks that could actually handle wheel bearing service on RV axles without guesswork, and what followed was a first-year story that covered everything from concrete slab prep to the first real job that rolled off the new equipment. We’re sharing it here because most shops considering this kind of investment want to know what the process actually looks like, not just what the brochure says.

Starting Point: Why Standard Lifts Don’t Fit RV Work
Most vehicle service lifts & jacks on the market are designed around passenger cars and pickups, which means their arm reach, spacing, and lift points assume a wheelbase far shorter than a travel trailer or Class A motorhome. This shop’s old setup — a pair of undersized rolling jacks and a scissor lift meant for cars — physically could not get under the axles of the bigger units coming through their door, and every wheel bearing job turned into an improvised exercise with wood blocks and extra hands. That’s not a workflow you can run safely at volume.
We started the conversation by mapping out their actual fleet mix: what percentage of jobs were travel trailers versus fifth-wheels versus larger motorhomes, and what the heaviest axle loads actually were. That data pointed us toward a mobile column lift system paired with adjustable-height rolling jacks for the axle work itself — the columns pick up the whole unit at the frame or axle points regardless of unusual wheelbase length, since the columns aren’t tied to a fixed rail spacing the way a traditional two-post lift is. For a shop with RVs and trailers of wildly different sizes coming through the same bay, that flexibility mattered more than raw lift capacity.
Concrete Slab Thickness and Rebar: What We Found
Before any lift equipment could go in, we had to deal with the floor. Mobile column lifts are lighter on slab requirements than a fixed in-ground system, but they still need a flat, structurally sound surface to travel on, and the columns themselves need adequate slab thickness under their travel path to avoid cracking under load over time. This shop’s existing slab, poured decades earlier for a much lighter era of vehicle service, tested out at roughly four inches with no rebar in the section where the columns needed to run.
For the weight class of RVs and loaded trailers this shop services, we recommended a poured section at six inches minimum with rebar reinforcement, tied into the existing slab rather than just poured on top of it. Skipping this step is the single most common mistake we see shops make with vehicle service lifts & jacks — a lift that’s rated correctly on paper can still fail against a slab that isn’t rated to support it. The concrete work took about a week including cure time, and it was the single biggest schedule item in the whole project, longer than the actual lift installation.
Install Day and the First Wheel Bearing Job
Once the slab cured, install itself moved fast. Our crew set the mobile columns, calibrated the wireless sync system so all units lift and lower together, and walked the shop’s technicians through the adjustable-height rolling jack controls — including the incremental lock positions that let a tech set the jack at a specific height rather than only choosing between fully down and fully up, which matters a lot when you’re working a wheel bearing job on a trailer that sits lower than an RV.
The first real job came four days later: a dual-axle utility trailer in for bearing replacement on all four wheels. The columns lifted the trailer evenly at the frame while the rolling jack isolated one axle end at a time for the tech doing the bearing work — no wood blocks, no jury-rigged support, and roughly half the time the same job would have taken on the old equipment. That job became the shop’s internal proof that the investment in vehicle service lifts & jacks, concrete included, was the right call.
What We’d Tell Any RV Shop Considering This Investment
Looking back at the full first year, a few things stand out. First, don’t underestimate the concrete question — if your shop building predates modern lift-rated vehicles, assume you’ll need slab work and budget the time for it, not just the cost. Second, mobile columns are worth strong consideration for any shop with mixed wheelbases, because the flexibility pays for itself in reduced setup time on unusual units. Third, pair your main lift system with the right rolling jacks from day one; trying to retrofit axle-specific tools later usually means buying twice.
This shop has now run a full year of wheel bearing jobs, brake work, and general service through the new setup without a single slab issue or lift-related delay. Their techs tell us the adjustable rolling jacks get used on nearly every job, not just bearing service, because the incremental height locks make positioning faster across almost any task. For an east-central Iowa shop working RVs and trailers, that first-year track record is exactly the kind of quiet, unglamorous reliability that vehicle service lifts & jacks are supposed to deliver — no drama, no downtime, just consistent capacity to do the work.
Maintenance Habits That Protect the Investment
A year in, this shop has settled into a maintenance rhythm that’s worth mentioning for any owner making a similar investment. They grease the column travel mechanisms on a set schedule, inspect cables and hydraulic lines monthly, and keep a log of hours run on each column so nothing gets skipped. Rolling jacks get the same attention — footpads checked for wear, hydraulic seals inspected before they leak rather than after.
None of that is complicated, but it’s the difference between vehicle service lifts & jacks that last fifteen years and equipment that needs early replacement because nobody watched it. We build a basic maintenance checklist into every install we do now, RV shops included, because the equipment is only as good as the habits built around it.
