RV Garages and Oversized-Height Shops in Southwest Missouri
Everything on this page runs off one number: the clear height of the opening you drive through. Get that wrong and nothing else can fix it.

Four questions. We call you back and talk through size, height and what it takes on your site.
Start at the roofline of the rig
A typical RV garage is 40 to 50 feet deep with 12 to 14 feet of clear door height (HomeGuide). Depth is easy to fix on paper. Height is not.
Clear height is not eave height. The eave is the top of the sidewall. The clear height is what is left after the door track, the header and the opener sit in that wall. The opening is always shorter than the wall. Plan the wall around the opening you need, not the other way around.
Measure the coach at its tallest hard point — the rooftop air conditioner, the satellite dome, the vent caps — not the brochure height. Then add clearance so you are not threading a needle in your own driveway every time you back in.
Doors at this size
A 14-foot door is not a 10-foot door with more panels. It changes the header, the wall framing above the opening, and often the truss. Overhead doors run $700 to $2,700 each and the tall ones sit at the top of that range before you add an opener sized for the weight.
Decide early whether the RV bay gets its own tall door with a standard door beside it for the truck, or one oversized opening doing both jobs. Two openings usually beat one giant one on both cost and daily use.
What height does below the floor
Greene County publishes post embedment as a table running 28 to 64 inches by truss span and eave height. A tall, wide RV building lands at the deep end of that table — closer to 64 inches than 28. That means more auger time, more concrete backfill and longer columns before a single sheet of steel goes on.
The county spec still governs the rest: minimum 6×6 treated posts, 10-inch holes with concrete backfill or 12-inch with soil backfill, 4 inches of crushed stone under each post, posts on 8 or 10 ft centers.
Slab and power
- A loaded coach puts heavy point loads on a few axles — the pour and the reinforcement get specified for that, not for a car. Slabs and site prep →
- Plan 50-amp service at the parking position if you shore-power the rig, plus normal shop circuits. Running it during the build costs a fraction of adding it after.
- Thinking about the boat too? A lean-to along one sidewall is almost always cheaper per covered square foot than widening the main building.
RV garage cost range
HomeGuide puts an RV garage at $50,000 to $160,000. That is a wide range, and the ends are predictable:
- Low end — one tall bay, a flat and dry site, a plain shell, minimal finish, standard doors.
- High end — 14 ft-plus clear height, 50 ft depth, multiple oversized doors, insulation, 50-amp power, heavier slab, and a site that needs cut and fill.
Ranges are market data, not our quote. What yours costs depends on site, height, doors and finish.

RV garage questions
- How tall does an RV garage door need to be?
- Most coaches need 12 to 14 feet of clear door height, per HomeGuide. Measure your rig at its tallest point — air conditioner, satellite dome or vent cap — then add a foot. Clear height is the opening you drive through, which is always less than the eave height.
- How deep should the building be?
- Typical RV garages run 40 to 50 feet deep. Measure the coach bumper to bumper, add room to walk past the rear, and add space for anything stored at the back wall. A 40-foot coach in a 40-foot building leaves you nothing.
- Do I need a thicker slab for a motorhome?
- A loaded coach concentrates weight on a few axles, so the pour is usually thicker than a car garage floor and the drive path gets the attention. Slab thickness, thickened edges and reinforcement get decided with the pad, not after.
