In-Ground Auto Lift for RV and Trailer Shops: First Year

An in-ground auto lift changes the math for RV and trailer service shops in a way most surface lifts can’t, mainly because long wheelbases and dual axles need drive-through clearance without a post landing in the wrong spot. We work with several shops in the Des Moines metro that service everything from travel trailers to Class A motorhomes, and the in-ground question comes up constantly during their first equipment purchase. This article walks through a first-year ownership story, from the used-versus-new decision to the first real service call, so you can see what actually happens after the sales conversation ends and the daily maintenance grind begins.

Why RV and Trailer Shops Look at In-Ground Lifts

Most RV and trailer shops start out with a portable or surface-mounted setup, then hit a wall once they’re servicing vehicles over 25 feet long. Posts and ramps eat floor space fast when the vehicle itself is the size of a small apartment. An in-ground auto lift solves that because the platform sits flush with the floor and the vehicle drives straight through without navigating around fixed columns.

For daily maintenance work — brake jobs, wheel bearing service, undercarriage inspections on trailers that have been sitting in Iowa weather all winter — that drive-through access saves real labor time. We’ve seen shops cut twenty minutes off every job simply by not fighting with positioning around posts. It adds up fast when you’re running six or eight vehicles through a bay in a day during the spring rush before camping season.

The Used vs New Decision Framework

The first real decision most shops face is whether to buy a used in-ground lift someone else is pulling out, or install new. We tell people to run three checks before considering a used unit: pit condition, cylinder age, and documentation. If the seller can’t produce install records or a recent inspection, assume you’re buying a project, not a working lift.

Used in-ground lifts can be a legitimate value play if the pit was properly sealed and the cylinder is under fifteen years old, but the labor to pull, inspect, and reinstall a used cylinder often closes most of the price gap versus buying new. New units also come with a warranty and a documented pit spec that matches current safety standards, which matters if you’re ever inspected by an insurer. Our general rule: if the used unit is more than half the price of new after you account for inspection and reinstall labor, buy new. The math almost always favors new equipment once you price out the hidden costs of an unknown cylinder history.

Sizing the Lift for Your Actual Fleet

RV and trailer shops routinely under-spec capacity because they’re thinking about the empty trailer weight, not the loaded weight customers actually bring in. We ask every shop to pull their heaviest expected vehicle — often a loaded toy hauler or a dually-plus-gooseneck combo — and size the in-ground auto lift to that number with margin, not to their average job.

Platform length matters just as much as capacity here. A lift sized for passenger cars won’t have adequate support points for a 32-foot trailer axle spread, so we spend real time during the sales process confirming platform dimensions against the shop’s longest regular customer vehicles. Getting this wrong means either turning away business or running vehicles outside the lift’s design envelope, which is a liability problem waiting to happen.

The Install: What Actually Happens

For the Des Moines metro shop we’re referencing here, the install ran through the same core sequence as any in-ground project: site evaluation, pit excavation, cylinder placement, concrete cure, then commissioning. The wrinkle with RV shops is drive lane width — we had to confirm the approach and departure angles gave enough clearance for a motorhome’s rear overhang, which isn’t something you worry about with a standard car lift.

We also spent extra time on the hydraulic line routing since this bay needed the platform positioned closer to a side wall than typical, to leave room for a second service lane. That meant longer hydraulic runs than a straightforward center-bay install, which changed the pump sizing recommendation. It’s a good example of why every in-ground auto lift install needs its own site-specific plan rather than a copy-paste spec sheet from a catalog.

First 90 Days: Daily Maintenance Reality

The first three months of ownership taught this shop more about daily maintenance habits than any manual could. Platform seals need visual checks weekly, not monthly, when the shop is running trailers with muddy undercarriages through daily. Grit and road debris work into seal edges faster than most owners expect, and catching wear early is far cheaper than a mid-season seal replacement.

The shop also learned to keep a log of every cycle count and any unusual sound during rise or descent, which turned out to be useful three months in when a slight hesitation on descent showed up. That log let our service tech diagnose a minor air-in-line issue over the phone before scheduling a visit, saving a wasted trip. Shops that skip logging tend to call us for problems that are already worse than they needed to be.

The First Real Service Call

Around month four, the shop called about a slow descent — the same kind of issue we hear about often, where a lift stops short of full travel and needs a look. In this case it turned out to be a minor hydraulic line restriction rather than a cylinder problem, and we cleared it on a single visit. That’s the value of catching things early: most in-ground auto lift issues in year one are minor and fixable if you call before the symptom gets worse.

We also used that visit to walk the shop’s team through basic troubleshooting steps for next time, since not every slow cycle needs a service call. Knowing when to check fluid level versus when to call for a technician saves both time and money over the life of the equipment, and it’s part of what separates a shop that gets ten trouble-free years out of an in-ground lift from one that’s constantly fighting it. If you’re weighing options, our lift buying guides and cylinder maintenance notes cover more of what to expect after year one.
