Yes, you can store a Class A motorhome in a metal carport, provided the structure is tall, wide, and long enough for your exact RV and is engineered for your local wind and snow requirements. For many Class A models, an 18 x 40 or 20 x 45 RV carport with at least 14 feet of height is a practical starting point.

Why Choose a Metal Carport for a Class A?
A Class A motorhome is a major investment, and its size can make enclosed storage difficult or expensive to find. A custom metal carport gives you dependable overhead protection from sun, rain, snow, falling debris, and seasonal weather without requiring you to rent an off-site storage space.
A steel carport is especially useful for owners who want convenient access before a weekend trip, need space to load supplies, or prefer to keep their RV at home. It also gives you a designated place for routine maintenance, washing, and pre-trip checks.
Our RV carports are customizable for large motorhomes, fifth wheels, travel trailers, and RV storage needs. Rather than choosing a one-size-fits-all building, you can design around the height of your air conditioners, the length of your motorhome, and the amount of clearance you need for doors, storage bays, and walkways.
What Size Carport Does a Class A Need?
The right Class A motorhome carport size begins with your RV’s actual exterior dimensions. Class A motorhomes are typically 35 to 45 feet long, 8 to 8.5 feet wide, and 12 to 13.5 feet tall. That measurement can increase once rooftop air conditioning units, satellite equipment, antennae, ladders, mirrors, awnings, and slide-outs are considered.
American Carports recommends that Class A motorhome owners consider a carport at least 14 feet tall, 14 to 16 feet wide, and 40 to 50 feet long. Many owners choose 18 x 40 or 20 x 45 as a more comfortable Class A starting point.
How Much Height Should You Leave?
Height is one of the most important measurements because an RV roof can be damaged by a carport that looks tall enough but lacks clearance for the tallest accessory. Measure from the ground to the highest point, not only to the top of the main roofline.
For many Class A motorhomes, 14 feet is the minimum practical height. A 16-foot leg height may be the better choice for a taller rig, an uneven driveway, a roof-mounted satellite dish, or extra clearance when pulling in.
Always account for:
- Roof-mounted AC units
- Satellite domes and antennae
- Roof ladders
- Uneven or sloped driveways
- Concrete thickness or future pad elevation
- The clearance needed while backing in
- Any door header, brace, or trim that could reduce usable entry height
Most Class A motorhomes need at least 14 feet of clearance, and 16 feet can be safer when rooftop equipment is included.
How Wide Should a Class A Carport Be?
A Class A coach can be more than 8 feet wide before mirrors and slide-outs. When slide-outs are extended, the total width can exceed 12 feet. A narrow carport may technically fit the vehicle but leave too little space to walk alongside it, access storage compartments, clean the exterior, or open a door safely.
An 18-foot-wide carport is often a good option for Class A motorhomes because it gives you side clearance for access and extended slide-outs. If you want a covered space for a tow car, golf cart, patio area, tool storage, or outdoor seating, choose a wider custom layout.
How Long Should It Be?
Length should cover the full RV plus practical entry and exit room. A 40-foot-long carport may fit a shorter Class A, while a 45- or 50-foot-long design can better accommodate larger coaches and allow a little space at the front or rear.
Measure the motorhome from the front bumper to the rear ladder, bike rack, hitch accessory, or spare tire. Then consider how you will approach the site and whether you need room to open a rear storage compartment or maneuver around the back of the coach.
Is an Open Carport Enough Protection?
An open metal carport provides valuable protection from direct sunlight, rain, snow, and falling leaves. For many owners, that is enough to reduce UV exposure and help keep the RV cleaner between trips.
However, open sides do not stop wind-driven rain, blowing snow, or dust. If your property is exposed to prevailing winds, sits near open fields, is located in a mountain pass, or experiences frequent storms, side panels can make the space more effective.
A partially enclosed design may include:
- One solid windward wall
- A rear gable end
- Side panels on one or both sides
- A closed end for privacy and weather protection
- A lean-to for tools, chairs, or camping gear
For full protection, a custom metal garage with an RV-height door is a strong alternative. Metal garages offer enclosed vehicle and property protection at a lower cost than a traditional garage.
What Roof Style Is Best for RV Storage?
A vertical A-frame roof is the best all-around option for most Class A motorhome storage projects. It provides a clean, finished look and helps rain, snow, pine needles, and other debris move off the roof more effectively.
This roof style is particularly important in climates with snow or frequent heavy rain. Vertical roof panels run from the ridge to the eave, which helps guide precipitation off the structure instead of across horizontal ribs.
American Carports identifies vertical roofing as the best choice for snowy climates. A-frame vertical roofs are designed to help snow, dirt, and rain slide off more easily.
Choose a vertical roof if you want:
- Better snow and rain shedding
- Less debris buildup
- A premium finish for a large RV structure
- A practical roof for a long, tall carport
- Better long-term performance in challenging weather
Does a Class A Carport Need Certification?
Your Class A motorhome carport may need engineering certification, a permit, or both, depending on where you live. Local requirements often depend on the building’s square footage, height, location on the lot, wind zone, snow zone, and whether the structure is anchored to concrete or ground-mounted.
High-wind regions may require a specific wind-speed certification and anchor plan. Snow-prone regions may require a specific snow-load rating, closer truss spacing, or heavier steel. Your local building department can tell you what applies to your address.
American Carports, Inc. structures can be engineered to meet wind-speed certifications required by local building departments. Higher snow loads can be accommodated through design choices such as closer truss spacing and heavier steel.
What Should You Ask Your Building Department?
Before ordering, ask:
- Do I need a permit for an RV carport?
- What wind-speed rating is required at my address?
- What snow-load rating is required?
- Are engineered drawings required?
- What setbacks apply near property lines, roads, wells, or septic systems?
- Is a concrete slab required?
- Are there height restrictions?
- Does my HOA need to approve the structure?
Taking these steps early can prevent avoidable redesigns or delays. If you are in an HOA community, obtain written approval before scheduling installation.
Can You Put a Class A Carport on Gravel?
A gravel base can work for some projects, but the correct installation surface and anchor system depend on the building design, soil conditions, local code, and certification requirements. A concrete pad is often preferred for a large Class A because it creates a level, durable parking surface and can support an appropriate anchoring system.
If you choose gravel, prepare it correctly. A stable, well-compacted base can improve drainage and help keep tires out of mud. However, do not assume gravel alone meets the needs of a certified high-wind or high-snow installation.
Talk with us about your site before you order. We can help you determine what information is needed to customize the structure, while your local building authority can confirm permit and foundation requirements.
What Other Features Should You Add?
The best Class A metal carport is designed for how you actually use the RV. You may only need basic overhead coverage, or you may want a more complete at-home RV storage area.
Popular upgrades include:
- Extra height for rooftop equipment
- An 18- or 20-foot width for walk-around room
- A longer layout for large coaches or rear accessories
- Side panels for wind and sun protection
- A vertical roof for runoff and snow shedding
- A closed gable end for better weather protection
- A wider custom design for a tow vehicle or golf cart
- An adjacent enclosed storage area for hoses, leveling blocks, chairs, and camping gear
- A custom building configuration that combines RV storage with workshop or equipment space
If you store supplies with your RV, consider adding a separate enclosed section rather than leaving valuable gear exposed. This can give you a convenient place for maintenance items, outdoor furniture, portable generators, and seasonal camping equipment.
