An RV and trailer service shop in Council Bluffs called us last spring with a specific problem: they needed a car lift automotive setup that could handle seasonal storage rotation on customer travel trailers AND service work on the smaller vehicles they occasionally took in. We are Auto Lift Services, an Iowa-based installer and parts supplier, and we quoted, delivered, installed, and have supported that shop for the past twelve months. This piece is the first-year story, covering how we sized the lift, what the electrical work required, how the seasonal storage workflow developed, and what the shop owner reports one year into ownership. It is not a sales pitch, it is the actual story.
Rotary and Challenger four-post lifts with extended runways for RV and trailer service, 14,000-pound capacity, rolling jack options, and seasonal storage-friendly geometry. Iowa install crews with parts pipelines behind every lift.
The Shop’s Situation Going Into the Purchase
The Council Bluffs shop is a family-run operation in a converted commercial building near the interstate, one bay, two people on the floor. Their bread-and-butter work is RV and trailer service: wheel bearings, brakes, axle work, and the annual pre-storage inspection that every wintering RV owner in western Iowa needs. They also do the occasional pickup or small-SUV service for existing customers, and they were losing that work because they had no lift and it was becoming a lie-under-the-truck job on gravel. Their goal was one lift that handled both use cases without buying two lifts.
The car lift automotive question for a mixed-use shop like this is not obvious. A two-post handles vehicles well but does nothing for a bumper-pull trailer that needs its wheels off for bearing service. A four-post drive-on is trailer-friendly and vehicle-friendly, but the standard-length runways in a general four-post are too short for anything but the smallest travel trailer. What we needed was a long-runway four-post rated for the heaviest trailer they would ever service, which pushed capacity to fourteen-thousand pounds and runway length to a minimum of twenty feet nose-to-tail.
Sizing the Lift: Capacity, Height, Configuration
We spec’d a 14,000-lb four-post extended-length drive-on lift with 22-foot runways, rolling jacks under the runways for wheels-off service, and standard eight-foot lift height. Fourteen thousand pounds of capacity was chosen to give margin over the heaviest tandem-axle travel trailer they would service; a fully-loaded 8,500-pound trailer at the tongue-plus-axle weight still leaves comfortable margin. The extended runways handle trailers up to 22 feet in length overall, which covers everything the shop reasonably serves. Anything larger than that is a fifth-wheel or motorhome and they refer it out to a larger operation.
Lift height was set at eight feet because their ceiling is nine-foot-eight clear; a full-height lift would have run into the ceiling with a mid-height trailer on top. Eight feet gives you working access underneath but requires a slight stoop for taller techs. Given the mix of work, trailer bearing service and occasional truck brake work, that ceiling constraint was the honest choice. We could have specced a lower-profile lift with less lift height for the vehicle work, but at that point the ergonomics dropped below the point where the shop would use it eagerly. Eight feet was the sweet spot. Every car lift automotive spec is a compromise between building constraints and workflow.
The Electrical Question: Single Phase vs Three Phase
Almost every RV service shop in a converted commercial building in Council Bluffs runs on single-phase 240-volt electrical. That is what this shop had, and it is what their car lift automotive power unit was spec’d to accept. Three-phase 208-volt is available on some larger commercial buildings and gives you slightly faster raise time with a smaller motor, but the wire and disconnect cost of installing a phase converter or three-phase service to a building that does not have it is significant. Single-phase 240 handles the lift’s power draw comfortably on a properly sized circuit.
The raise time question is worth discussing. A three-phase power unit on the same four-post lift raises a loaded lift about fifteen seconds faster than a single-phase unit. Over a thousand cycles a year that is four hours of raise-time saved. Meaningful in a high-volume shop, negligible in a low-volume storage-focused workflow. For the Council Bluffs shop the raise-time savings were not worth the cost of upgrading the building’s service. We stayed with single-phase and the lift has performed exactly as expected in every operating condition through the year.
Circuit Requirements and Panel Upgrades
The lift required a dedicated 30-amp double-pole 240-volt circuit run from the shop’s main panel to a disconnect box mounted near the lift’s power unit. The circuit run was short; the panel was about twenty-five feet from the lift’s power unit position, and the shop’s electrician installed a new breaker, a fused disconnect, and the whip to the power unit in about half a day of work. The circuit specification came from the lift’s electrical page in the install manual, which we shared with the electrician a week before install so the work was done and inspected before our crew arrived.
The other electrical item was the compressed-air line for the safety-lock releases. Most four-post lifts release their safety locks with a small air cylinder that requires 90-to-120 PSI of shop air. The Council Bluffs shop’s existing compressor was adequate, and we ran a half-inch nylon line from the compressor tank to the power unit. Compressed air is often forgotten by first-time buyers on their car lift automotive install; do not forget it. The lift will function without air but the manual lock-release becomes a pain within a week of use. Plumb the air line before we arrive.
Freight and Install Day
Freight from Ames to Council Bluffs is a two-day run via a common carrier through Omaha for the final leg. The four-post extended lift shipped as two long crates on a single pallet, plus a smaller crate for the power unit and hardware. Total freight was roughly 3,400 pounds. The shop borrowed a forklift from a neighbor to offload, a forty-minute favor that saved a lift-gate charge and made the offload smooth. Crates were staged along one wall of the bay overnight before install day so nothing sat outside in the weather.
Install was a full day with our two-person crew. Anchor drilling on the concrete slab, column base plates set and bolted, runways lifted into place with the same borrowed forklift, hydraulic lines routed, air line connected, electrical whipped into the pre-installed disconnect. Empty cycles to prime the hydraulic system, then a loaded cycle with the shop’s own truck. A car lift automotive install of this size takes about seven hours of actual wrench time, call it eight hours including cleanup and paperwork. The shop was operational the next morning at open.
The First Season of Storage Workflow
By late fall the shop had developed a clean seasonal storage workflow. Customers dropped off travel trailers over a two-week window in October. Each trailer was inspected, bearings checked, brakes exercised, and then lifted to the top of stroke for storage through winter. The four-post’s runways cradle the trailer wheels off the concrete, which the shop owner believes helps tire longevity and eliminates the flat-spot problem that shows up on stored trailers sitting on cold concrete for four months. Customers loved the offering and repeat business locked in.
What surprised the shop owner was how much service work flowed through the same lift alongside the storage. On days when they were not lifting a trailer for storage rotation, they were lifting a pickup or small SUV for brake or transmission service. The car lift automotive setup was the single piece of equipment that unlocked both revenue streams, storage fees for eight months of the year and service revenue every week. The lift paid for itself inside nine months on combined revenue. That was well ahead of the twelve-to-eighteen-month projection we quoted at the sale.
One Year In: What Works and What They Would Change
One year in, the shop reports the lift has cycled about seven hundred times and needed nothing beyond routine maintenance. Cables have been greased twice, hydraulic fluid checked and topped once, safety locks cycled and inspected quarterly. Zero warranty calls. What they would change: they wish they had specced the rolling jack accessory at the time of purchase rather than adding it two months later. Buying the jack up front would have saved shipping and would have gotten the wheels-off workflow into their routine sooner and cheaper.
The other thing they would change is the layout of the disconnect and the air line. Both were placed on the wrong side of the power unit for their bay layout, and they have to walk around the lift to reach the shutoff. Small annoyance, not worth the cost to move. If you are planning your own car lift automotive install, ask the installer to place the disconnect and air line on the side of the power unit closest to your entry. It costs nothing at install time and saves you a hundred walks a year for the life of the lift.
