Essential Gear: RV Covers

Originally Published in Trailer Life Magazine

Cloaking a stored RV with the right cover protects the exterior finish from exposure to the elements and keeps it looking its finest

Statistics show that RVs are stored for long periods of time. While you might imagine your RV is relatively safe from theft or vandalism during the off-season, it’s actually under constant attack by the sneakiest vandal of all — nature ­­— which bakes it with ultraviolet rays and attacks it with moisture. This is why you need an RV cover to stand guard and protect your investment.

UV rays are one of the biggest hazards unprotected RVs face. Prolonged exposure to direct sunlight breaks down the paint, gelcoat, and vinyl graphics, but there’s more at stake than a dull finish on a once-bright surface. Paint protects the surface underneath, whether metal or fiberglass. Once the paint goes, the surface underneath begins to degrade. UV rays also turn plastic and soft rubber parts dry, brittle, and discolored.

Then there’s the effect the environment has on the roof. Sealants on an unprotected roof degrade faster, and the dreaded black streaks can form on the sides of the RV, which can be devilishly difficult to remove. As the sealants degrade, leaks can develop…and you know the rest.

It’s important for a cover to be vented, or include panels made of a breathable fabric, to prevent moisture from getting trapped underneath. Cheap plastic tarps, typically found in hardware and home-improvement stores, promote mold, mildew, and rust, not to mention the fact that the tarp can abrade the RV and cause serious damage. A good cover will have vents to release trapped moisture and a top made of a fabric like Tyvek, which lets moisture out but keeps water from getting in. A good cover also includes a padded underside, which, properly used, will not be abrasive to the RV surface. Most covers are available in models designed for specific climates, such as heat and bright sun, or snow and constant rain.

The fit is as important as the fabric. A loose-fitting cover can billow, making installation a hassle. It can also flap in windy conditions, rubbing the paint and roof, causing damage, and snagging and tearing the fabric on sharp corners. Covers come in semi-custom sizes, cut to approximately the dimensions of an RV, or are custom made specifically to a set of measurements you provide. Be sure to measure the RV yourself, and do not rely upon model numbers from the manufacturer. Because a snug fit results in stress in some areas, the best covers come with reinforced corners.

RV covers are secured by straps running underneath from side to side, and across the front and back. Weighted toss bags let you slide the loose end of the straps under the RV. Some covers come with these, but you can use almost anything that can be tied to the end of the strap. For extra points, train your dog to crawl under the RV trailing the strap for a treat on the other side.

Even the best RV cover will wear out in time, but there’s no point in hurrying the process. Before installing a cover, go on the roof and sweep off any debris that could scratch the paint when the cover is snugged down. Even though you vacation every year, gravity never does, so make sure you’re wearing nonslip shoes.

Fold down or remove any antennas, and make sure there are no exposed sharp edges from solar panels and other accessories. Use pool noodles or shop rags to cover sharp edges on the roof. Sharp edges along the bottom of the RV should be smoothed out where they can make contact with the cover. Tape a few shop rags or an old T-shirt over them, and use adhesive remover to get rid of the tape adhesive later.

Tire covers are equally important for protection against the elements. Trailer tires are made with chemicals added to the rubber compound that fight UV, but they don’t last forever. Also, the tires on the sunny side of a parked RV are subject to more exposure than those on the shady side and might deteriorate sooner. Clean the tires with warm soapy water before you cover them. Avoid tire dressings with alcohol, petroleum distillates or silicone.

Most cover manufacturers sell repair kits to patch rips or holes. If repair is not possible, balance the expense of a new cover against the damage it prevents to your RV, and the numbers come out in your favor every time.

Here’s a roundup of some of the most popular RV covers for towables. There’s sure to be one among them that will make your rig wake up from its storage slumber bright-eyed and ready for the open road.
