CarCover5-Ply Top FabricLifetime WarrantyGold Shield 5L Class C RV Cover -- 18 to 20 Feet (5RV-CC-1820)

Full-season protection for Class C motorhomes in the 18-to-20-foot length range. The Gold Shield 5L uses a five-layer top panel and three-layer sides with a micro-porous film core to block rain, snow, UV rays, and road grime while still letting trapped moisture escape -- so your paint, seals, and finish stay clean and dry whether you store for a weekend or an entire winter.

Built for Real RV Storage Conditions

Most entry-level RV covers are either waterproof-but-suffocating or breathable-but-leaky. The Gold Shield 5L addresses both failure modes with a laminated micro-porous film sandwiched inside the polypropylene PLUS plies. Water droplets cannot penetrate inward, but water vapor generated inside the cover can escape outward -- the same principle used in quality outdoor gear. That means no condensation pooling on roof seams, no mildew growing under slide toppers, and no musty smell when you open the door in spring.

The cover is purpose-shaped for Class C body profiles. The top panel extends downward over all four sides to protect the transition zone where roof meets sidewall -- the area most vulnerable to wind-driven rain. Elastic hems lock the front and rear corners into place, and an adjustable buckle system cinches the mid-body tight so the cover does not balloon and flap in wind. Double-line stitching at all panel junctions keeps seams from separating under long-term UV exposure.

5-Ply Top Construction

Four polypropylene PLUS plies plus one micro-porous film layer block over 98% of UV rays and all rain and snow. The top layer is the heaviest, most reinforced panel on the cover.

3-Ply Sides

Two polypropylene PLUS plies and one micro-porous film layer protect sidewalls while saving weight. Sides remain flexible in cold temperatures so installation is not a struggle.

Breathable Micro-Porous Film

The film layer blocks liquid water while passing water vapor. This prevents rot, mildew, and moisture buildup underneath the cover -- critical for long-term storage in humid or rainy climates.

Fit and Security System

Slip-seam body shaping, elastic front and rear hems, and an adjustable buckle system combine to keep the cover snug against the RV in wind without pressure points that abrade the finish.

Access and Ventilation Features

You should not have to remove the entire cover every time you need to access the door, service bay, or shore-power connection. The Gold Shield 5L includes heavy-duty zippered panels sized for motorhome entry doors. Built-in air vents positioned in the lower sections of the cover promote passive airflow from ground level upward, further reducing interior humidity during storage.

  • Zippered entry panels for door and compartment access without removing the cover
  • Built-in vents on lower panels promote passive airflow and reduce moisture
  • Ladder cap panel protects the cover fabric from sharp ladder rungs
  • Gutter protection panels reinforce areas where rain gutters contact the fabric
  • Reflective panels on sides improve low-light visibility when parked near traffic
Blocks Over 98% of Dirt and Dust

The tightly woven polypropylene PLUS plies prevent airborne particulates from reaching the RV surface. Useful in desert storage yards, agricultural areas, or any site with consistent dust exposure. Less washing means less chance of swirl marks on painted surfaces.

Installation Process

No tools are required. The cover ships folded into a storage bag sized to fit in a basement compartment. Installation is a two-person job for most Class C owners -- one person feeds the cover over the roof from a ladder while the other guides it along the sides. Weighted buckle straps hang down and can be caught and secured from ground level without climbing. The elastic hems self-locate at the front cap and rear corners once the cover is positioned correctly.

Sizing Note

This cover (5RV-CC-1820) is sized for Class C motorhomes with an overall length of 18 to 20 feet. The cover's own dimensions are 20.5 ft long x 8.83 ft wide x 9.08 ft tall -- the overage provides the material needed to wrap down all four sides. Measure your RV's total length including any rear ladder, bike rack, or cargo carrier before ordering.

Long-Term Storage Maintenance Tips

Keep Your Cover Performing Season After Season
  • Rinse the cover with a garden hose once or twice during storage to remove airborne contaminants that can slowly abrade the surface
  • Use the included patch kit immediately on any small punctures or tears -- micro-porous film repairs best when addressed early
  • Remove the cover during sustained winds above approximately 60 mph if possible; the buckle system handles normal gusts but not extreme storm events
  • Store in the included bag off the ground and away from rodents; polypropylene is not a food source but rodents will nest in fabric folds
  • Allow the cover to dry fully before folding and storing to prevent any mildew growth in the bag
Compatible AC Unit Clearance

The Gold Shield 5L top panel is designed to accommodate up to three rooftop air conditioning units without creating pressure points that could crack AC shrouds or stress the cover seams. If your Class C has an unusually tall or wide aftermarket AC unit, confirm the cover height spec (9.08 ft) clears your specific installation.

Important Information
  • This cover fits Class C motorhomes with an overall length of 18 to 20 feet only. Do not attempt to use on longer vehicles -- improper coverage leaves seams and roof edges exposed to weather.
  • Measure your RV's total length including rear-mounted ladders, bike racks, or cargo carriers before ordering. External accessories can add 1 to 3 feet to the effective length.
  • The cover is water-resistant, not fully waterproof. The micro-porous construction is designed for long-term storage ventilation. In extreme or extended downpours, some surface moisture migration is possible at seam areas.
  • Do not install over a dirty or wet RV -- abrasive grit trapped under the cover can scratch painted surfaces. Wash and dry the RV before covering.
  • Remove cover during extreme wind events (sustained winds above approximately 60 mph) to prevent stress on straps and buckles.
  • Allow the cover to dry completely before folding into the storage bag to prevent mildew growth inside the bag.
  • Not intended for use while the RV is in motion. Cover must be fully removed before driving.
Protecting your RV with a quality cover is essential for maintaining its value and longevity. RVs are significant investments that are often exposed to harsh weather conditions, making them susceptible to damage from corrosion, mold, and UV rays. Unlike standard vehicles, RVs serve as mobile homes for many, and a cover can provide added insulation and privacy, enhancing your comfort while protecting against the elements. By investing in an RV cover, you reduce wear and tear, ensuring that your RV remains in excellent condition for years to come.

How To Measure Your RV:

Length: Measure the longest two points from the front to the rear of RV, including bumpers, spare tire, and ladder.

Height: Measure the highest point of the RV sidewalls from the top of the roof down to the outside frame, excluding ground clearance, roof-mounted accessories, vents, and A/C units.



How to Install Your RV Cover:

1. Identify the front of the cover by locating the "Front" tag on the interior.
2.
Lay the cover lengthwise on the ground, inside out, with the exterior facing up.
3.
Fold the sides toward the center and roll the cover from the rear, leaving the front end loose.
4.
Position the rolled cover at the rear of the RV near the ladder.
5.
Loosen the roll slightly, then climb the ladder while holding the front end.
6.
Pull the cover onto the roof gradually until you have a strip covering the entire roof.
7.
Starting at the front, unfold the cover side to side, letting it drape down the sides as you move to the rear.
8.
Ensure the corner opposite the ladder is positioned under the cover’s corner.
9.
Climb down while bringing the cover down with you, then adjust the cover as needed.

Removal:

1. Undo all straps and zippers on the cover.
2.
Lift the front of the cover to the top of the RV.
3.
Pull the cover down from the rear.

For Cleaning:

Proper care of your RV cover is essential for maintaining its performance and water resistance. Contaminants like dirt and grease can damage the cover, so regular washing is recommended for long-lasting protection.

You can wash the cover by hand or in a washing machine. For hand washing, install the cover on your RV, rinse it with a hose, then use a cloth and multi-purpose cleaner to scrub. Rinse again and either towel dry or let it air dry.

For machine washing, use the largest machine available, set it to gentle mode, and wash with mild powder detergent in cold water—avoid bleach and fabric softeners. Rinse the cover twice to remove all detergent, and always air dry.
