Popular Metal RV Garage Sizes
The size 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 Class | Garage Door Height | Minimum Garage Size |
|---|---|---|
| Class A | 14 ft. | 18 ft. x 50 ft. x 16 ft. |
| Class B | 12 ft. | 20 ft. x 24 ft. x 14 ft. |
| Class B+ | 12 ft. | 12 ft. x 25 ft. x 14 ft. |
| Class C | 14 ft. | 26 ft. x 48 ft. x 16 ft. |
| Super C | 14 ft. | 24 ft. x 48 ft. x 16 ft. |

Sturdy Steel Framing
Your metal building will be constructed with premium steel studs. Choose between 14-gauge framing for general-purpose buildings or heavier-duty 12-gauge framing for additional strength and durability. The 12-gauge steel framing offers enhanced resistance to severe weather and includes a 20-year rust-through warranty. If you’re planning to use your building for many decades, 12-gauge framing is a wise investment.
Our extra-wide buildings feature sturdy steel trusses to safely bridge wide spans without any columns, as shown below.
Durable Roofing
For roofing, you can choose between 29-gauge steel panels or thicker, commercial-grade 26-gauge panels. The 29-gauge panels are ideal for mild climates. The 26-gauge panels are perfect for areas that regularly get snow or harsh weather, or those who want to maximize their building’s longevity.
Classy Siding
The siding of your building will be crafted from steel panels with the same gauge as the roofing, ensuring consistent quality and durability. Choose between horizontal or vertical siding based on which style you prefer, seen below.
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 for people, we offer two styles of walk-in doors: one with a window, and one without. We also have two different styles of windows available.
Insulation
When customizing your building, choose from three insulation options:
- Woven R17 insulation: Effectively reduces condensation buildup. This insulation controls hot and cold temperature 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.
Color Options
Choose between a wide selection of colors for your roof, trim, and siding. For a more classy look, consider our two-tone (wainscot) option, which features a different color on the lower portion of your building.
Our metal garage kits for sale are usually available in the following colors:
Concrete Slab Size and Cost
Foundation Installation:
Most metal buildings require a concrete slab foundation. Unfortunately, we are not 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.

Frequently Asked Questions
The size of the garage you need depends on your RV class size. Remember that you may need additional door height if your RV has A/C units or antennas.
| RV Class | Garage Door Height | Minimum Garage Size |
| Class A | 14 ft. | 18 ft. x 50 ft. x 16 ft. |
| Class B | 12 ft. | 20 ft. x 24 ft. x 14 ft. |
| Class B+ | 12 ft. | 12 ft. 25 ft. x 14 ft. |
| Class C | 14 ft. | 26 ft. x 36 ft. x 14 ft. |
| Super C | 14 ft. | 24 ft. x 48 ft. x 16 ft. |
The cost of your RV garage will depend on the exact size, style, and options you choose.
An 18×35 RV garage with 14′ sides and a 12×12 garage door starts at a little less than $10,000 in most locations. That’s a reasonably small investment when you consider the value of the RV that your garage will be protecting. A similar-sized RV carport is about half the cost of an RV garage.
To provide the best protection for your RV from weather elements, we recommend the following customizations:
- 12-gauge tubing for thicker, more durable framing.
- 26-gauge sheeting for a stronger, more resilient roof.
- Woven R-17 insulation for optimal temperature and moisture control.
