Popular Metal RV Garage Sizes
The size of the garage you need depends on the class size of your RV or motorhome. If you have antennas or A/C units on the top of your RV, you may need to increase your garage door height.

RV-Ready Garage Considerations
A true RV garage needs more room than a standard carport or storage building. Height, width, and garage door clearance are the big factors to check before you order, especially if your motorhome has roof add-ons like A/C units, solar panels, or antennas.
Key features to look for when configuring a metal garage for RV storage:
- Typical height range: 12–14 ft high
- Interior footprint:
- Small camper: 20–30 ft long
- Mid-size recreational vehicle: 30–40 ft long
- Large Class A: 45–50 ft long+
- Width range: Usually 18–30+ ft to allow room to walk around the RV once parked
- Roll-up or sectional door: Wide enough for mirrors and safe entry; often 10–12 ft wide, larger doors available
- Framing: Standard steel framing, with upgrades available for heavy wind or snow regions
- Roof style: Vertical roof recommended for faster runoff in snow and rain
- Enclosure choice: Fully enclosed for security and weather protection; side or end openings optional if preferred
- Access options: Add walk-in doors and windows for easier entry and ventilation
- Expansion space: Many owners add extra length or a lean-to for tools, outdoor equipment, a golf cart, or a second vehicle
- Moisture and comfort: Insulation, vents, or windows help reduce condensation and keep stored RVs in better condition
- Engineering: Where required, certified buildings can be ordered to meet local wind/snow requirements

A Guided Tour Inside Your RV Garage
Here’s a quick look inside the high-quality metal RV garage you’ll get from Alan’s Factory Outlet.
Sturdy Steel Framing
Sturdy steel framing features include:
- Premium steel studs
- 14-gauge framing for general use
- 12-gauge framing for added strength
- Steel trusses for wide spans

Durable Roofing
Durable roofing options include:
- 29-gauge steel panels for mild climates
- 26-gauge steel panels for snow, harsh weather, and long-term durability

Classy Siding
The siding of your building will be crafted from steel panels with the same gauge as the roofing.

Choose between horizontal and vertical siding based on your preferred style, as shown here.

Garage Doors, Walk-In Doors, and Windows
We have a variety of roll-up garage doors available from 6’x6′ up to 16’x16′ in size. Chain hoists are also available for purchase.

For easy entry, we offer two styles of walk-in doors: one with a window and one without. We also have two different window styles available.

Insulation
When customizing your building, choose from three insulation options:
- Woven R17 insulation. Effectively reduces condensation buildup. This insulation controls hot and cold temperatures with an R-value of 17, suitable for more demanding temperature environments.
- No insulation. Choose this if you aren’t concerned about condensation buildup or temperature control.
- Double Bubble insulation. Helps reduce condensation buildup. This insulation only has an R-value of 1, which is ideal for minimal insulation needs.

Concrete Slab Size and Cost
Foundation installation
Most metal buildings require a concrete slab foundation. Unfortunately, we aren’t able to install the foundation. You’ll need to prepare this before your building can be scheduled for installation. Your local planning or building department can provide specific foundation requirements for metal buildings in your area.
Slab sizing
Typically, your slab should be slightly larger than the metal building. Use our online concrete pad size calculator to determine the correct slab size for your location. If local regulations require an additional ledge, it can be sloped or lowered to prevent water from pooling next to your building’s base rail.


Cost Estimates:
In most areas, the cost to pour a concrete slab starts at approximately $8 per square foot for small metal buildings. For larger structures, the cost ranges from $4 to $10 per square foot. Consider pouring the foundation yourself to save money. Concrete is relatively inexpensive, and DIY can significantly reduce costs.

RV Cover vs. RV Garage vs. Paid Storage Lot
There are several ways to keep your RV safe. Some protect better, some save money, and one gives you both.
Common choices for motorhome storage and security:
- Fabric RV covers. Lightweight and portable, but they can tear, blow off in high winds, and don’t fully protect against pests or extreme weather.
- RV garages/motorhome garages. Steel structures built to fit your vehicle, offering full coverage from sun, rain, snow, and animals. Unlike fabric covers, a metal RV garage provides durability, security, and peace of mind for long-term storage.
- Paid storage units. Convenient for urban areas, but monthly fees add up quickly (as high as $250+ per month). Over time, investing in a metal garage or camper storage building can save thousands compared with renting space.
With an RV garage from Alan’s Factory Outlet, you get the perfect building for your vehicle right at your property, which protects your investment and can double as extra storage for tools, ATVs, or outdoor gear. No recurring rental fees to worry about.
For those not ready for a full garage, we also offer Metal RV Carports, roof-only structures that provide reliable protection from sun, rain, and debris while keeping costs lower.
Tailored RV Garage, Your Way
Have a specific layout in mind? Our 3D RV Garage Builder makes it simple to create a custom floor plan that exactly fits your camper, RV, or more (3-car garage options available). Choose your building size, roof style, sidewall height, and add features like roll-up doors, walk-in doors, bays for your tools or extra vehicle, or even extra living space.
Whether you want a fully enclosed detached garage or a simpler RV carport, this tool helps you design the right metal structure for your needs. Build, customize, and schedule your new home garage today with Alan’s Factory Outlet.
FAQs About Metal RV Garages
For the best protection, we recommend:
- 12-gauge tubing for a stronger, more durable frame
- 26-gauge roof sheeting to withstand the elements
- Woven R-17 insulation to control temperature and moisture
These will keep your RV safe and in great shape!
The cost of an RV garage will depend on size, style, and features. For example, an 18×35 RV garage with 14′ sides and a 12×12 door will be under $10,000. If you want something more budget-friendly, a similar-sized RV carport is half the price.
It depends on your RV’s width and height, especially if it has rooftop A/C units or antennas. Leave extra overhead clearance so you don’t hit anything when you park!
Absolutely! An RV garage will protect your vehicle from the weather and add $10,000 to $20,000 to your home’s value. It’s a smart investment that gives you peace of mind and keeps your RV in great shape for years to come.
