The Complete Guide to RV Covers

A steel RV cover is the most durable way to protect your recreational vehicle from sun damage, hail, and snow. Unlike fabric tarps that tear or trap moisture, a metal structure offers permanent protection that extends the life of your RV. This guide covers everything you need to know about sizing, roof styles, customization, installation, and financing for rv covers.

What Is a Metal RV Cover?

A metal RV cover is a steel structure designed specifically to shelter recreational vehicles. It typically features an open design with a roof and partial sides to allow airflow while blocking direct sunlight and precipitation.

Key Components

Structural Elements

• Galvanized steel frame with square tubing
• Corrugated sheet metal roof and wall panels
• Trusses or bows supporting the roof
• Base rails anchored to concrete or ground
• Legs spaced every 5 feet for support

Material Benefits

• Fire resistant and weatherproof
• Protects against UV damage to paint and decals
• Prevents hail damage
• Low maintenance
• Lasts 30+ years with proper care

RV Covers vs Standard Carports

An RV cover is taller than a standard carport to accommodate campers and motorhomes. Key differences include:

• Standard carports: 7 to 10 feet tall
• RV covers: 12 to 14 feet tall (up to 16 feet for large Class A motorhomes)
• RV covers include extra bracing for wind resistance at greater heights
• RV covers account for roof-mounted equipment like air conditioners

How to Size Your RV Cover Correctly

Getting the dimensions right is the most critical step. You must measure your RV yourself rather than relying on manufacturer specs, which often list interior space instead of actual bumper-to-bumper length.

Why Accurate Measurements Matter

Common Mistakes

• Using manufacturer spec sheets instead of measuring
• Forgetting roof-mounted equipment like air conditioners
• Not accounting for slide-out extensions
• Measuring body instead of bumpers

Consequences of Wrong Sizing

• RV does not fit under structure
• Damage to roof equipment
• Cannot open slide-outs
• Costly modifications or rebuild needed

Determining the Right Height

Measure from the ground to the very top of your air conditioning unit or satellite dish.

Height by RV Type

• Travel Trailers (10-12 feet tall): Need 12-13 foot cover
• Fifth Wheels (12-13 feet tall): Need 13-14 foot cover
• Class C Motorhomes (11-12 feet tall): Need 12-13 foot cover
• Class A Motorhomes (12-13 feet tall): Need 14-15 foot cover

Height Guidelines

• Add 6 inches minimum clearance above tallest point
• Add 12 inches for easier maneuvering
• 12 feet: Sufficient for most travel trailers under 35 feet
• 14 feet: Recommended for Class A motorhomes

Determining Width and Slide-Outs

Standard widths are 12 feet, 18 feet, or 24 feet.

Width Planning

• Single slide-out travel trailer: Needs 18 foot cover
• Double slide-out fifth wheel: Needs 20-24 foot cover
• No slide-outs: Can use 12 foot cover
• Measure with all slide-outs fully extended
• Add 24 inches on each side for clearance

Important Width Limitation

• Do not exceed 24 feet wide for roof-only structures
• Wind lift risk increases above 24 feet
• Wider structures require side panels for safety

Determining Length

Metal America measures length by frame base, but the roof extends 6 inches on each end.

How to Measure

• Measure from front bumper to rear bumper
• Include hitch extensions and bike racks
• Do not rely on manufacturer specifications

Pricing Increments

• Buildings 30 feet wide and under: Priced in 5-foot increments
• Buildings 32 feet and wider: Priced in 2-foot increments
• A 33-foot RV costs the same as a 35-foot cover
• Always round up to next increment

Length by RV Type

• Small travel trailer (under 25 feet): 25-30 foot cover
• Mid-size trailer (25-30 feet): 30-35 foot cover
• Large trailer (30-35 feet): 35-40 foot cover
• Fifth wheel (35-40 feet): 40-45 foot cover
• Class A motorhome (35-45 feet): 40-50 foot cover

Anchoring Systems

Proper anchoring is critical for structural integrity and safety. Insufficient anchoring is the leading cause of metal building failures. Never cut corners on this essential component.

Why Anchoring Is Critical

What Anchors Do

• Prevent uplift during high wind events
• Transfer roof loads safely to foundation
• Keep structure from sliding or shifting
• Required for warranty compliance
• Mandated by all building codes

Consequences of Poor Anchoring

• Structure can blow away in high winds
• Warranty becomes void
• Insurance may deny claims
• Building fails inspections
• Risk of property damage and injury
• Costly repairs or total loss

Concrete Wedge Anchors

The most reliable anchoring method for structures on concrete slabs.

How They Work

• Expansion-style anchors grip inside concrete
• Installed after building is positioned
• Holes drilled through base rails into slab
• Anchors driven into holes and tightened
• Expansion creates mechanical lock in concrete

Specifications

• Diameter: Typically 1/2 inch
• Embedment depth: 4 inches minimum
• Quantity: One anchor per leg minimum
• Two anchors per double or ladder leg
• Concrete strength: 3,000 PSI minimum
• Cure time: 7 days before installation

Installation Process

1. Building positioned and squared on slab
2. Installer marks hole locations through base rails
3. Hammer drill creates holes in concrete
4. Dust and debris cleaned from holes
5. Wedge anchors inserted and tightened
6. Torqued to manufacturer specifications
7. Final inspection of all anchor points

Slab Requirements for Best Results

• Level within 3 inches across entire surface
• Correct size to match building dimensions
• Fully cured (minimum 7 days, prefer 28 days)
• No major cracks or deterioration
• Minimum 4 inches thick (6 inches for large buildings)
• Proper rebar reinforcement
• Adequate strength rating

Advantages of Concrete Anchors

• Strongest anchoring method available
• Long lifespan with minimal maintenance
• Best option for permanent installations
• Meets all building codes
• Required for habitable structures
• Professional appearance

Mobile Home Anchors

Used for ground installations on dirt, gravel, or grass surfaces.

Description and Function

• Auger-style anchors screw into ground
• Look like large corkscrews
• 4-inch wide helical blades
• Flat plate on top for base rail attachment
• Penetrate 30 inches into soil

How to Calculate Quantity Needed

• Formula: (Building Length + Building Width) × 2 ÷ 10
• Example 1: 12×20 cover = (12+20) × 2 ÷ 10 = 6.4, round up to 7 anchors
• Example 2: 18×35 cover = (18+35) × 2 ÷ 10 = 10.6, round up to 11 anchors
• Example 3: 24×40 cover = (24+40) × 2 ÷ 10 = 12.8, round up to 13 anchors

Installation Process

1. Anchor positions marked based on leg locations
2. Auger driven vertically into ground
3. Top plate positioned flush with ground surface
4. Base rail bolted to anchor plate
5. Soil compacted around anchor
6. All anchors checked for proper depth

Soil Considerations

• Work best in firm, compacted soil
• Clay soil provides excellent holding power
• Sandy soil may require additional anchors
• Loose soil needs compaction before installation
• Rocky soil may prevent proper installation
• Hardpan may require alternative anchoring

Important Notes

• Not included automatically with purchase
• Must be specifically added to order
• Cost: $35 per anchor installed
• Required for buildings 31+ feet wide
• Highly recommended for all ground installations
• Proper installation critical for wind resistance

Common Questions About RV Covers

How long does an RV cover last?

With proper maintenance, 30+ years. Lifespan depends on climate, gauge, and maintenance. Coastal environments may see 20-25 years.

Can I install it myself?

No. Professional installation required. Improper installation voids warranty and creates safety risks. Requires specialized equipment.

How long does installation take?

1 to 3 days depending on size. Simple 12×20 may take one day. Large 24×50 may take 2-3 days.

Do I need a concrete slab?

No. Many install on dirt or gravel with mobile home anchors. Concrete provides most stable foundation and is required for enclosed garages.

How much snow can it hold?

Standard rating: 25-35 PSF (2-3 feet of heavy wet snow). Vertical roofs shed snow better than horizontal.

Will my RV fit?

Measure carefully from ground to highest point with all equipment. Measure width with slide-outs extended. Measure length bumper to bumper. Add clearances.

Can I enclose it later?

Yes, but plan garage door height during initial construction. Cannot raise legs later. Build taller initially if future enclosure possible.

How do I prevent rust?

Touch up scratches immediately. Clean regularly with mild soap. Inspect twice yearly. Galvanized steel resists rust but not rust-proof.

Do metal buildings attract lightning?

No more than other structures. If struck, steel safely conducts charge to ground. Proper grounding important if adding electrical.

Can I add solar panels?

Requires engineering approval. May void warranty if improperly installed. Contact us before adding to discuss options.
