Class B RV Covers & Carports 
 Small Footprint, Serious Protection

Owning a Class B motorhome is all about balance. It’s big enough to feel like home, yet small enough to park almost anywhere. But even when you’re not driving it, your RV is still sitting under the sun, the rain, and whatever the seasons throw at it. And no matter how compact it is, weather exposure can be surprisingly unforgiving.

That’s where a custom steel RV cover from Pro Metal Buildings makes a real difference. Built to fit the exact size and shape of your Class B, our metal carports give your motorhome long-lasting shelter without the constant hassle of fabric covers or the expense of a full garage.

Why Even a Small RV Needs Big Protection

It’s easy to think that a smaller rig means less to worry about. The truth is, Class B RVs face the same weather risks as larger motorhomes, and sometimes they wear faster because they’re used more often. Leaving yours uncovered can lead to:

  • UV rays fading paint, drying seals, and weakening roof materials
  • Moisture buildup causing rust, mildew, and mold in hidden spots
  • Tree sap, branches, and animal mess marking and staining the exterior
  • Snow and ice putting stress on vents and seals during winter
  • Extreme heat damaging interiors and electronics over time

A steel RV carport protects your investment year-round, with none of the frustration that comes with tarps or seasonal fabric covers.

Built to Fit Your Class B Motorhome

Most Class B RVs measure between 17 and 22 feet in length, 7 to 8 feet in width, and up to 10 feet in height when you include rooftop accessories like air conditioners or antennas. We custom-build your cover so it fits perfectly, without wasted space or awkward overhangs.

Suggested carport dimensions for Class B RVs:
 Width: 12 feet
 Length: 25–30 feet
 Height: 12–13 feet

If you’re unsure of your exact measurements, our RV Measurement Guide will walk you through the process.

Metal Carports vs Fabric RV Covers

Fabric RV covers may seem like a quick fix, but they often wear out faster than expected and can be a hassle to install. Here’s how a metal carport compares:

FEATURE

Lifespan
Weather Protection
Daily Access
Maintenance
Value

FABRIC RV COVER

2–5 years
Moderate
Inconvenient
High
Short-term

STEEL RV CARPORT

30+ years
Excellent in all seasons
Easy walk-in clearance
Almost none
Long-term investment

For even more protection, we also build fully enclosed metal garages with lockable doors and insulation.

Custom Options for Your RV Shelter

Every Class B RV cover we build is tailored to your needs and your site conditions. Choose from regular, A-frame, or vertical roof designs. Decide between open-sided, partially enclosed, or fully enclosed layouts. Pick a color that matches your home or shop. We can anchor the structure to gravel, concrete, or dirt and add features like windows, doors, insulation, and side storage extensions.

If you want ideas, our Metal Carport Gallery has dozens of completed builds from real customers.

Designed for Your Climate

We don’t send cookie-cutter kits. Every structure is engineered to meet your local codes, wind speeds, snow loads, and permitting included.

Some examples: 

  • California, Nevada, Arizona – Reflective metal panels and open-vent design to beat the heat
  • Oregon, Washington, Colorado – Reinforced frames with certified snow-load ratings
  • Texas, Florida, Gulf Coast – Hurricane-rated anchors and wind-braced frames
