Protect your RV with a garage designed for height, clearance, and durability. Our prefabricated steel RV garages reduce construction time and labor costs while providing a reliable structure supported by a 50-year warranty.
Sales and use tax are not included in price. Buildings are designed using standard keyway foundation and SteelMaster does not provide installation services. All projects are sold as DIY.
*Exclusions apply; see warranty for details.
*Arches are priced in standard 22-gauge and may not meet your snow and/or wind load requirements. Buildings can be designed in thicker steel to meet higher wind and heavier snow loads. Consult with your building specialist for further details.
Every aspect of your Quonset can be designed to fit your needs. SteelMaster offers add-ons, or you can locally source these building options.

Looking to add a two-car garage to your property? SteelMaster’s DIY RV garage kits are engineered to accommodate taller heights, wider spans, and longer lengths needed for motorhomes, trailers, and oversized vehicles. Each structure can be customized to meet your storage needs, site conditions, and local building requirements.
Before building, it’s important to make sure your RV garage meets all local codes and engineering standards. RV garages are larger structures, so understanding permits, load requirements, and zoning rules early helps avoid project delays.
Our RV garages are engineered to comply with IBC and ASCE-7 building standards and are designed around your local wind, snow, and seismic loads. Because RV garages are typically taller and wider than standard garages, it’s imperative to confirm what local zoning, height restrictions, and permits are necessary with your city or county.
Every RV garage kit includes free state-stamped, engineer-approved drawings prepared by a licensed professional engineer. These plans are usually suitable for permit submission and meet the requirements of most building departments.
Our RV garages use a minimum steel thickness of 22 gauge, which is substantially thicker than the industry standard of 26 gauge. The steel is premium, high-strength grade 80 material with an 80,000 PSI yield strength. Thicker gauges may be specified when required to meet local code, snow loads, wind loads, or increased height requirements common with RV garages.
Understanding the full cost of an RV garage upfront helps prevent surprises. RV garages often require larger components, so knowing what’s included and what’s optional is key when budgeting.
The base kit provides everything needed for the structural shell:
Additional costs may include state and local taxes, foundation work, site preparation, and installation labor. Optional accessories can be added to your order or sourced locally, including:
RV garages are backed by a 50-year rust-perforation warranty, the longest in the industry, providing long-term protection and peace of mind.
SteelMaster can assist with the engineering and blueprint details for your building, but before reaching out, it helps to have a general idea of what you want for your RV storage.
Class A, B, and C motorhomes, as well as travel trailers, can all be stored in a steel RV garage kit. Since RVs typically measure 20 to 45 feet long, 8 to 10 feet wide, and 10 to 14 feet tall, your building should be sized slightly larger to allow for clearance.
If you plan to store more than just your motorhome, opting for a larger building gives you that extra space.
Unless you’re building an RV carport or an open-ended RV garage, you’ll need to select a garage door for your building.
Garage and service doors can be supplied by SteelMaster for an additional cost or purchased locally. Your SteelMaster project manager will plan accordingly based on your choice.
Most customers choose to build their own endwalls with local materials, as it’s typically more affordable.
Others prefer SteelMaster’s steel prefabricated endwalls or decide to keep their building completely open-ended.
If you have the land, financing, and a general plan for steps one through four, you’re ready to talk with a SteelMaster building specialist to confirm your pricing.

RV garages require additional height, clearance, and door sizing compared to standard garages. Planning your layout carefully ensures your RV fits comfortably now and in the future.
RV garages are available in a wide range of widths, lengths, and heights to accommodate different RV classes.
With proper sizing, an RV garage can accommodate your RV along with storage, tools, or a workspace. The clear-span interior design means there are no interior support columns, so all interior space is usable.
Doors, vents, and framed window openings can be included in your RV garage design. Garage doors to accommodate your RV’s height are the most common add-on.
Door size and placement depend on the garage width and RV height, and wider garages can often accommodate both a large garage door and a walk-in entry door. Building specialists can help you determine the best door sizes and configurations.
Yes. RV garages can be designed with doors on both endwalls for a pull-through layout.
Because the endwalls are non-load-bearing, they can be fully customized and built using the materials and door configurations you prefer, including doors on both ends.
Your building specialist can help design an endwall layout that fits your RV size, access needs, and future use plans.
Is it possible to make the RV garage bigger in the future?
Yes. RV garages can be lengthened later by adding additional sections in two-foot increments, allowing you to expand if your storage needs change or you upgrade to a larger RV.
Can the RV garage be repurposed if I sell my RV?
Yes. RV garages can be repurposed as workshops, storage buildings, or mixed-use spaces. The clear-span design and ability to add length later make them highly adaptable long-term structures.
RV garages are larger than standard garages, so understanding the build process helps you plan labor, equipment, and timelines.
Many customers choose to assemble their RV garage themselves to save on labor costs, while others hire a contractor due to the size and height of the structure. The level of help needed depends on your experience and the garage dimensions.
Installation time varies by size and complexity. A team of at least three people can typically raise six to eight arches per day. For example, a 40-foot-long (20 arches) RV garage can often be assembled in two or three days for the shell of the building, depending on width and height.
Yes. Each RV garage includes a construction manual. Our customer service team is available to answer technical questions and walk you through the process if needed. We also provide step-by-step overview videos on our YouTube channel.

An RV garage is a long-term investment designed to protect a high-value vehicle.
When properly installed, RV garages are designed to last 50 years or longer, often outlasting traditional wood-framed buildings.
The steel panels are coated with Galvalume Plus, a thick, organic corrosion-resistant coating that protects against rust, UV exposure, and harsh weather.
No regular painting or sealing is required. Periodic inspections after severe weather are recommended and typically sufficient.
RV garages are engineered to handle heavy snow loads and high wind speeds when designed for local conditions, making them suitable for all climates.
Comfort and moisture control become more important when storing an RV long-term.
Insulation is optional and typically recommended if the RV garage will need to be heated, cooled, or used as a workspace. For basic RV storage, insulation is often unnecessary.
Condensation can be managed through ventilation, vapor barriers, or insulation. Planning airflow during the design phase helps reduce moisture buildup.
es. RV garages can be insulated and finished later to support heating or cooling systems if your needs change.
